Announcing Duxbury DBT for Mac 12.7 sr3

DBT 12.7 sr3
2024-04-11 (2023-04-17)

Duxbury Systems continually revises DBT to add new features, support new and updated embossers, and fix problems, as well as to respond to the latest revisions in braille rules, operating system updates, and third party changes.

Below you will find our advances and improvements since the prior release.

For more sources of information, please take advantage of "Check for Updates" from your DBT Help menu. Or, visit the Duxbury Website for both new information and historical information about DBT features and updates.

Service Release SR3 is free to all licensed users of DBT 12.7. It includes these fixes as improvements.

• Chuvash, Ingush, and Udmurt are identified as European, not Asian languages.
• Some uncommon contraction errors in English/Unified (UEB) have been corrected.
• Support for Cherokee and Navajo has been added.
• Croatian support has been updated and improved to match the latest specifications we have. Uncontracted braille is now the default.
• Swahili translation has been adapted specifically for Kenya. DBT now offers a Swahili (Kenya) template that supports a contracted braille code that appears to be used only in Kenya, and a Swahili (General) template for use elsewhere.
• We have increased the range of characters that can be imported into DBT, with particular increases in the characters to be imported into the Arabic, Hindi, and Devanagari scripts.
• DBT now imports the long division symbol (U+27cc) properly from MathType. In addition, the Nemeth Code templates properly translate the long division sign and barred brackets from print to braille and back to print again.
• Styles in the English BANA pre-UEB templates have been adjusted so that documents containing math give better support for Nemeth Code.
• There is a new template specifically for uncontracted UEB with Nemeth, to avoid the problem of switching into contracted braille following math segments.
• There are five fonts packaged with DBT: Braille, SimBraille, Braille Français, SimBraille Français, and Swell Braille. Each of these has been updated to version 3.1, incorporating these improvements:
• Encoding of Unicode Braille Patterns characters U+2800 through U+283F as well as Unicode U+2011.
• Improved appearance when ClearType is enabled. This change also applies to display of braille documents in DBT. Please note that disabling ClearType remains preferred.
• Technical fixes that may sometimes have prevented proper rendering, particularly of Braille, Braille Français, and Swell Braille.
• Braille-Build has been fixed and updated to generate version 3.1 fonts.
• Use of <esc>Pnn for Braillo 650SW embossers is restricted to values of nn 01-99. This corrects a problem with embossing certain larger documents.
• We have fixed a problem with single-sided output on classic Enabling Technologies embossers when a page contains graphics.
• The columnar table formatter is better able to handle tables with a few columns, some of which have lots of text.
• A bug that caused unnecessary "failsafe" formatting of tables has been fixed.
• A bug has been fixed to correct formatting of tables on pages witih antipicatory page headings, as used in the UK.
• The Word importer now correctly imports certain Word text boxes that were previously missed.
• The translated line display has been improved, to allow display of all or most codes. Use the "Formatted View Translated Line Codes" control in the Gobal View Preferences dialog to set this up.
• The translated line display for BANA with Nemeth documents eliminates spurious display of shall and which.
• DBT command line processing has been fixed. DBT will now exit now after processing files with /brf option or similar options, unless one or more files is opened using the command line as well.
• On some computers, DBT was prone to crashing when selecting certainly Edit menu items after closing a document. This has been corrected.
• An [mfcs] code without a corresponding [mfce] code will no longer cause DBT to lock up.

DBT 12.7 sr2
2023-10-03 (2023-10-02)

Service Release SR2 is free to all licensed users of DBT 12.7. It includes these fixes as improvements.

• Handling of Nemeth in two templates, English (BANA Pre-UEB Textbook DE) - BANA and English (BANA Pre-UEB Textbook DE) - BANA Nemeth, has been corrected.
• English/Unified (UEB) braille-to-print translation has been improved. The same improvements are included in all the learning tables.
• Croatian braille-to-print translation has been improved.
• Serbian braille-to-print translation has been improved.
• Placement of the second page of a two page table has been corrected.
• When importing math as UEB with Nemeth, a problem in DBT 12.7 caused the loss of the space after problem numbers in a list of problems within the Nemeth switches. This problem has been fixed.
• Preference file names have been regularized. (Through this release, each new release ignores the user settings of prior versions. This will not happen from this point forward.)

DBT 12.7 sr1
2023-9-06 (2023-9-11)

DBT 12.7 SR1 has been released free to all users of DBT 12.7 to fix a few critical issues:

• A new problem causing crashes with tabular material has been fixed.
• DBT does not crash when you set a window of fewer than 9 lines.
• Import of braille files using "Orbit Reader" no longer favors uppercase. This improves subsequent braille-to-print translation.
• There is a new template "Haitian Creole". The translation is identical to French uncontracted.
• DBT can now read characters beyond U+FFFF; it supports 54 new Unicode ranges beyond this limit. These are largely ancient languages and additional Asian scripts. The most requested scripts are Cuneiform and Ugaritic. Click here for an external web page for the details.

DBT 12.7
2023-8-04 (2023-8-07)

DBT 12.7 provides the following important improvements and fixes and more.

Document Importing

• Importing .docx files avoids an unusual pitfall that could cause a DBT crash.

Document Exporting

• HTML and Word exports can reconstruct hyperlinks from DBT markup when a URL is included. Importers for HTML and .docx files produce the appropriate markup, so hyperlinks can, in effect, be preserved round-trip through braille.
• HTML and Word exports can be customized.
• HTML and Word exports improve handling of many DBT styles, producing better indent and runover in the output.

Math

• Nemeth math-only print-to-braille translation has been updated to prevent insertion of unwanted script indicators in certain instances.
• Nemeth math-only braille-to-print translation has been updated for miscellaneous improvements including to the handling of typeform indicators and math styles.
• Improved recognition of the start and end of math when importing Word documents.

DBT Operations / General

• Find and Replace dialogs support limited wildcard use in codes.
• A new parameter in the [ind] code allows for right alignment of many lines of text.
• The menu and dialog in the Global menu formerly labeled Autosave Options is now labeled File Locations. You can use this dialog to set default locations for Open and Save dialogs. The dialog still allows for management of autosave options.
• DBT supports a new command line switch /resetfilesavefolder or /resetfileopenfolder for use when the Save As dialog or Open dialog will not appear, or appears only after a long delay. Please contact technical support for help using this.

Language Updates

Flag	Description

DBT 12.6 sr1
2022-12-8 (2023-1-12)

Duxbury Systems continually revises DBT to add new features, support new and updated embossers, and fix problems, as well as to respond to the latest revisions in braille rules, operating system updates, and third party changes.

Below you will find our advances and improvements since the prior release.

For more sources of information, please take advantage of "Check for Updates" from your DBT Help menu. Or, visit the Duxbury Website for both new information and historical information about DBT features and updates.

DBT 12.6 SR1 provides the following important improvements and fixes and more.

Reference Page Numbering

Reference Page Numbering, also known as Print Page Numbering, is an important formatting feature of textbooks and other documents where collaboration with inkprint readers is important. DBT 12.6 SR1 has made several important improvements to the handling of Reference Page Numbering:

• DBT's formatter can automatically increment reference page numbers in both print and braille documents.
• The code used to trigger automatic incrementing can be assigned to the keyboard shortcut used for introducing new Reference Page Numbers, by using the Shortcut Preferences Dialog in the Global menu.
• Importing page break locations from Word (.docx) files now works with modern desktop versions of Word and on Windows 10 and Windows 11.
• For users of Duxbury's BANA Template for Microsoft Word, we've made one other improvement. Where a RefPageNumber paragraph style is used in the middle of a list, DBT will automatically convert this to a RefPageNumberEmbed style to avoid erroneous skipped lines in the list.

Accessibility

• The Canute Braille E-Reader is now supported by DBT.

Document Importing

• We corrected imports of files tagged for spelling/grammar when Word uses the bidi attribute instead of the val attribute to mark the language. This affects, in particular, .docx files containing blends of English and Hindi.
• There are several fixes for importing Word documents with MathType expressions. These changes fix problems with use of the prime symbol and accidental use of a forced hyphen. Importation of function names followed by a Greek letter is also fixed.
• Custom importers (command lines specified in dbt.uit) are no longer restricted to eight-bit command lines, and the command lines are essentially unlimited in length. This makes is more generally possible to use a custom importer on any given document file, regardless of the name and location of the file.
• Custom importers may produce UTF-8 output, provided that a Byte Order Mark is placed at the start of the file. The Byte Order Mark is three bytes: 0xEF, 0xBB, 0xBF. DBT will not compress spaces for UTF-8 custom importer output files, as it does for customer importer output files encoded as DUSCI.
• DBT can properly import indexed roots ([ixtrs]...[ixrte]) from OpenXML (.docx) mathematics markup.
• Importing .docx files containing numerous footnotes and/or endnotes is now more stable, uses less memory, and is faster.

Document Exporting

• Korean text is exported properly to .prf files (but only when UTF-8 encoding is selected)

Math

• We have changed the math style in the templates English (BANA Pre-UEB Textbook DE) - BANA Textbook Fmt and English (BANA Pre-UEB Textbook DE) - BANA Nemeth. Instead of using the codes [ts] and [te] to switch into and out of technical notation, the math style now switches into and out of the Nemeth translation table. This change makes the translated line meaningful for Nemeth technical notation in these pre-UEB templates.
• See other math changes in the language improvements.

Embosser Support

• DBT now supports Z-fold format on Index FanFold embossers
• QuickTac and similar (.sig format) graphics may be produced on ViewPlus embossers, when embedded in a DBT document.
• A problem that caused DBT to improperly scale TactileView images on ViewPlus embossers has been fixed.
• We have fixed a DBT bug that caused excessive popup errors when embossing to Nippon Telesoft Super Gemini embossers with interline print.

DBT Operations / General

• The G1Passage style has been added to all UEB templates. This should be used for spelling lists and similar items as directed by the UEB rule books.
• We have corrected the processing of modified End Codes in Custom formatted tables of contents.
• We have corrected two issues with Replace All in the Editor. The first problem is that the Replace All logic will miss a code (or, presumably, text) that is to be replaced the second (and fourth, etc.) time where it appears immediately after itself. The second problem is a popup message that reports DBT is unable to locate a cursor when Replace All is complete.
• DBT better supports two-page tables. These are tables whose rows spread between two braille pages.
• A potential for DBT to lock up during translation has been resolved.
• Minor updates have been made in the UKAAF template to improve formatting, including of poems.

Language Updates

Flag	Description
	All Languages of India: fix apostrophe
	Assamese: Repair some letter combinations
	Hindi: handle English in braille to print.
	Khakas: (adding a new language); This is a minority language spoken in Russia
	Lithuanian: Respecting emphasis in braille to print.
	Nemeth Code: fix spacing issues near boldface and a few other things.

We have made several "internal" improvements, with potential impact on other languages, including Cherokee, Canadian Aboriginal languages, Japanese, and several West African languages, though these improvements are not fully exposed in the update. If you are interested in this work, or any other language improvements, please write to us at languages@duxsys.com.

DBT 12.6
2022-4-15 (2022-4-25)

DBT 12.6 provides the following important improvements and fixes and more.

User Interface/ Commands / Accessibility

• DBT Editor, Coded View: improved display of non-breaking spaces, non-breaking hyphens, and assisted hyphens.
• Cut and Paste in the SEARCH and REPLACE Dialog: When working on a braille document, the DBT editor now allows cutting and pasting codes containing the tilde (~) and other non-braille characters.
• Replace All: This editing function has been revised for stability and should always produce the expected result.
• For the Mac platform, greatly improved cursor routing support with refreshable braille displays.

Embosser Support

• Super Gemini Embosser:  Duxbury added support in DBT (Win) for variations in the font used for interline print.
• Index Embossers and Humanware (Enabling) Embossers: NEW! Selecting DP6 (double-sided landscape z-fold embossing) versus DP7 (single-sided landscape z-fold embossing).
• Braillo 300, 300 S2, 450 S2, 600, 600 S2: The page length specifications for A4 paper on all these models has been updated (to 83 x 117).
• Enabling Embossers (the classic models that support graphics): Both center and right alignment of tactile graphics output as specified.

DBT Operations / General

• Command line processing: has implemented the command line switch /RemovePrinterInfo, used when saving custom DBT templates.
• The command line now handles wide Unicode characters for file names that can appear in world alphabets.
• Editing: Duxbury fixed a number of customer issues including a reported crash under certain circumstances of saving a file, and a problem inserting a Word document into an open DBT editing session when using Coded View with JAWS and UI Automation.
• Templates: Updated the "English (UEB) - UK formatting (UKAAF)" template to cure problems in SWIFT.
• Activation: Minor improvements to the activation wizard.
• DBT Installer: A bug that could install the support file "en/actwiz.mo" multiple times has been fixed.

Document Importing

• Math Type imports: We resolved a problem in trigonometric functions such as sin, cos, tan, etc., when followed by a Greek letter; the needed space after the function name is now present.
• Orbit Reader imports / BRL Files: the Orbit Reader import filter has a change to ensure that the braille dot patterns dot 4, dots 45, 1256, 246, 12456, and 456 are mapped to the preferred ASCII character to allow recognition by the braille-to-print translators. This makes the Orbit Reader Import filter a good choice when importing .brl files from any refreshable braille device.

• LaTeX: improvements cover additional cases of emphasis/typeform indicators in the markup.

Language Updates

Flag	Description
	Languages of India: Bengali, Gujarati, Kannada, Malayalam, Oriya, Panjabi, Sinhala, Telugu. The accuracy of the braille-to-print translations for these Indian languages has been improved.
	All eleven official languages ofSouth Africa: have fully functional braille-to-print translators suitable for demanding applications (Afrikaans, English, and the nine indigenous languages: Ndebele, Nguni, Sotho, Swati, Tsonga, Tswana, Venda, Xhosa, and Zulu).
	Mathematics Braille: There is a correction for the "identical to" symbol (dots 456 123456) in the English (UEB) braille-to-print table and in 11 non-English braille-to-print tables: including Afrikaans, Welsh, Irish, Biblical Original Languages, Esperanto, and several of the indigenous South African languages.
	Amharic: The print-to-braille translation table, and braille-to-print table, are updated to correct the representation of the Amharic syllable "do", and to extend support for the "simplified mode."
	Biblical Original Languages tables improved.
	Danish, Greenlandic: The translation tables in both directions, print-to-braille and braille-to-print, have been updated to correct handling of certain indicators, including emphasis and termination of capitals, and to remove pre-UEB American-style English braille as a secondary language. The associated Danish (and Greenlandic) uncontracted tables were likewise updated.
	English / UEB: The English/Unified Braille translation tables, both print-to-braille and braille-to-print, have been updated to disallow interior type form changes within words standing alone, which affects short-form usage in rare cases. They also correct the contraction usage of several unusual words, and include the recent decisions of the UEB Code Maintenance Committee. The "learning series" (partial contraction) tables for BANA: TSBVI Clusters, Mangold Method, and NLS I.M.B.T.; those for UKAAF/BAUK: Braille in Easy Steps, Fingerprint (UEB), and Take off Series; and OTHERS: RNZFB STAR and S.A. Syllabus Level are included in these updates. If you wish us to include your language's curricula for learning tables, please contact us at: languages@duxsys.com.
	Finnish: The braille translation tables in both directions, print-to-braille and braille-to-print, have been updated to correct emphasis indicators and a punctuation mark.
	Quebec French, Pre-Unified: The print-to-braille table corrects the encoding for a square shape input character.
	Greek: The print-to-braille table is updated to correct the encoding of dasia in the entry for alpha upsilon with varia and dasia.
	Igbo: NEW! This language now has a braille-to-print (reverse) translation table. Also, the print-to-braille translation table is updated to correct the representation of several characters.
	Latvian: The braille translation tables in both directions, print-to-braille and braille-to-print, have been updated to conform to newer standards for certain indicators and punctuation marks.
	Mathematics – Nemeth Code: The Nemeth translator already adds spaces around many signs of comparison including all of the common ones. This handling has just been added for double length arrows. Also, when a comparison sign is at the end of a math style, the translator now correctly adds a space before the sign but not after it. In addition, we fixed a problem that could cause the omission of a baseline indicator needed after a term with subscripts and/or superscripts when followed by a trigonometric function.
	Romanian: The print-to-braille translation table has been updated to provide support for Cyrillic characters, still sometimes found in Romanian and Moldovan text.
	Serbian: Improved braille-to-print translation including the correction of two non-alphabetic symbols in Cyrillic text.
	Slovak: Updated print-to-braille & braille-to-print tables for a number of symbols specified by the Slovak braille authority. Also, fixed the local encoding to enable correct Slovak braille display.
	Slovenian: Because of recent contact with Slovenian braille experts, we have reworked the Slovenian print-to-braille table. The changes include the typeform indicators (bold, italic, etc.), and the decimal comma. A corresponding braille-to-print table has been developed, and a new template added for grade 1 (uncontracted) Slovenian braille.
	Swedish: has improved translation tables in both directions, print-to-braille and braille-to-print, respecting certain punctuation signs and emphasis indicators.
	Urdu: The print-to-braille translation table has been updated to correct the representation of the Arabic letter "heh goal" (Unicode: U+06C1).

DBT 12.4 sr1
2019-03-07 (2019-03-12)

Primarily, this service release resolves issues reported with respect to specific embossers.

• For Columbia embossers, this release realigns the front to back registration, restoring the correct spacing.
• For the Interpoint Elekul 55 (Belgium), output has been fully updated to restore all functionality. (A Reminder: It is important that the path to PRINT55.EXE be properly set in the Device Settings tab of the Global Embosser Setup. A newly created embosser setup will have this set correctly by default.)
• The TranSend SE embosser has a restored font list.

In addition:

• We have modified DBT's .bru importer w.r.t. importing notetaker .brl files. (These braille files are typically formatted with each paragraph as one long line.) If you begin your .brl file with the four characters "_%_:", the DBT importer treats the file as Nemeth Code in UEB context, causing it to automatically assign the styles math and math-TextInMath where appropriate. This handling matches the .brf file importer handling for .brf files starting with those four characters.
• - We have revised and updated the DBT Help files, focusing on the topics that describe the different braille translators. We hope that customers gain a better understanding of the Duxbury DBT translators through our efforts to improve our documentation.

The core of Duxbury DBT and its translators has not changed.

DBT 12.4
2018-12-20 (2019-01-03)

Major Improvements

• For lengthy file imports, DBT now displays a progress bar.
• DBT opens files faster, with quicker performance in general operations.
• In UEB templates, there is a new chemistry style. For any technical notation within the chemistry style, there is no use of word or passage capital indicators, as each capital letter is capitalized separately.
• The NEW Bristol Braille Canute Mk13 Braille eReader is supported as an embosser.
• Graphic images in centered headings are now well handled.
• The BANA Listed Tables format is restored.
• The insertion of [hl] codes is no longer restricted when importing DAISY or XML files, as it is for Word files.
• The biggest additions in languages are starter tables for the Arabic, German, Russian, and Spanish math (technical notation) braille systems. These braille math codes may impact braille production in over 80 countries.
  • Templates for these four languages all have a math style. For example, if you use the math style in a German template, you get German math braille. For ease of use, the math style is inserted automatically when you import a LaTeX file.
  • The Russian math translator affects technical braille for many languages: Armenian (Eastern), Azerbaijani, Belorussian, Bosnian, Bulgarian, Chinese, Chuvash, Croatian, Czech, Estonian, Georgian, Hungarian, Ingush, Kazakh, Kirghiz, Latvian, Lithuanian, Macedonian, Montenegrin, Polish, Russian, Serbian, Slovakian, Tajik, Tatar, Turkmen, Udmurt, Ukrainian, Uzbek.
  • The Arabic language and unified Arabic braille rules are used in over 25 countries.
  • The Spanish language and unified Spanish braille rules are used in about 20 countries.
  • You are invited to test the math braille translators and send suggested improvements to languages@duxsys.com.
• Sample files for over a hundred languages are incorporated into the DBT Help so that you can quickly test DBT in an unfamiliar language.

Mathematics Braille

• UTF-8 conversion is now built into our LaTeX importer. This allows non-ASCII characters in the text: unusual accented letters, non-Roman scripts such as Cyrillic, Greek, Hebrew, Arabic, Hindi, etc., to be imported directly into DBT as combined text and math in a single step.
• The LaTeX importer now treats the code $$, when adjacent to a tab character, as the start or end of displayed math.
• The LaTeX importer no longer generates a space in cases where a LaTeX or MathType passage includes a "thin space". These extra spaces caused unneeded braille indicators in some math translators.
• The LaTeX importer no longer ignores some absolute value signs.
• The LaTeX importer now handles Greek letter variant forms, the so-called blackboard characters, and some additional special characters.
• Handling of reference page indicators in UEB with Nemeth is improved.
• The ending codes for the math style have been refined. We have moved the [i] code to the end, which prevents the insertion of the grade 1 indicator before certain punctuation marks, such as the question mark.

Embossers

• DBT can now generate interline print for Gemini embossers.
• DBT supports the ViewPlus "Tiger" registry key and enforces a 0.5 inch minimum top margin for the Columbia embosser.
  • The Columbia model, with a top margin setting of 0 now has an effective 0.5" top margin. A top margin setting of 1 has an effective 0.65" top margin. For higher top margin settings in DBT, the effective margin is 0.4" times the number entered in DBT.
• For dual ink and braille embossers, DBT eliminates most inappropriate gaps in the inkprint text.
• DBT codes no longer appear in the interline print of embosser output.
• For entries in the printer queue, DBT no longer adds "(Ink)" to the document name when not appropriate.
• DBT now prints TactileView (TV) Images to the Columbia embosser - and presumably other ViewPlus embossers - at the intended size. Note that the image size is not set directly from DBT, but DBT ensures that the size should be the same in the output as on screen. (Note: the size is determined by the image height, and images that are too wide for the page are likely to be clipped. For such images, direct output from TV may be the appropriate approach.)

Language Updates

According to the 2013 UNESCO document World Braille Usage, Arabic Pre-2002 is the official Arabic translator for Bahrain, Iran, Malaysia, and Indonesia. DBT now has a template for the Pre-2002 Arabic translator.

To assist those studying ancient languages, a new template and translator for the transcription of Semitic Languages has been added.

The English UEB translation table was changed to allow the functionality of the chemistry style, and also to refine the contraction use in a series of uncommon words.

Language Improvements

Flag	Description
	Arabic: adds a math-only print-to-braille translator invoked by using the math style. (Note: preliminary.)

	Hindi: braille-to-print improves handling of single and double quote marks.
	Portuguese: some improvements in the handling of punctuation.
	Russian: adds a math-only print-to-braille translator invoked by using the math style. (Note: preliminary.) The braille-to-print translator improves the translation of certain letter/number combinations.
	Slovenian: the template now reserves the bottom line of each page for braille page numbers with no preceding text.
	Spanish: adds a math-only print-to-braille translator invoked by using the math style. (Note: preliminary.)
	Ukrainian: the template now shows the capital letter sign in braille.
	Uzbek: the translators reflect a minor change in the braille translation rules that removes an ambiguity about the braille 'e'.

DBT 12.2
2017-08-25 (2017-08-25)

Duxbury Systems continually revises DBT to make fixes, respond to braille rules changes, and to add new features. The list below covers only changes since the last release. For the most recent information; possibly newer than that included here, please take advantage of Check for Updates from the Help menu. Or, visit the Duxbury Website for both new information and historical information about features and updates.

Primary Areas of Improvement

• Translated Line is greatly improved and more responsive.
• Math improvements (see below)
• Contains new BANA 2017 Word Template with numerous improvements.
• DBT Templates are now readable text files. This allows skilled users to assemble their own templates much more easily.
• New Template for users in the United Kingdom: English (UEB) - UK Formatting (UKAAF)
• New Table of Contents Style - UK Basic - which follows UKAAF formatting recommendations.
• Improvements to the UEB translator (Unified English Braille) (see below)
• New embossers and embosser improvements (see below)
• TactileView integration repaired.
• Improved Help Content.
• Many internal efficiency improvements.
• Language improvements (see below)

English UEB

• Now supports document-specific Typeform Indicators as defined in the UEB Rules of Unified English Braille Section 9 for inkprint attributes that carry meanings the braille reader needs to know about . A range of such indicators can be defined such as the use of Script Font, Text Color or Highlight Color, as well as Drop Shadow and Outline Text. See the new user interface in the Global: Word-Importer dialogue.
• Certain currency expressions, when marked as "technical notation," no longer give rise to an unnecessary grade one word indicator.
• When a sequence of single capitalized letters is treated as a passage, the last such letter is included in the passage.
• If [ps]...[pe] (i.e. superscript) codes immediately surround a trademark symbol (U+2122), they are now discarded as redundant.
• Contractions of several uncommon medical terms have been improved.

New Embossers and Embosser Fixes

• Support for the Braillo 300 S2 has been added to DBT.
• TranSend SE is now supported on Romeo 60 and Juliet 120.

Math Improvements

• For translating into Nemeth Code in UEB context, we have solved a problem that caused intermittent errors at the start of math sections, such as a missing numeric indicator for a number at the start of a Nemeth Code section.
• When importing a LaTeX file (from Scientific Notebook or another source) to create Nemeth Code in a UEB context, DBT now correctly suppresses the terminating and starting Nemeth indicators where there should be a "pass through in math" section; it also puts in the "one-word switch" where appropriate.
• When importing math for Nemeth Code in UEB context, embedded text in a math expression that occurs inside a pass through in math section no longer causes problems.
• The translated line no longer drops spaces in certain locations. Specifically, use of the math style now does not cause a space to be dropped on the translated line.
• When importing a LaTeX file that uses the command \includegraphics, the DBT document now gives the filename of the graphics file.

User Interface

• The Global, Word-Importer dialogue has a new option for mapping font characteristics to transcriber-defined Typeform Indicators for English UEB.
• Selecting the correct language for Han character import now happens automatically with the choice of a DBT template. (Previously this selection always had to be done manually from the Global, Import Options dialogue, and that option is still allowed if the user wishes to continue to specify the choice directly.)
• DBT updates documents immediately when certain global options are changed.

Miscellaneous Changes

• We have improved the display of the translated line in formatted print documents for languages that introduce discretionary hyphens.
• We have added two spaces to the formatted-view translated line at each place where a tab code is present in the markup.
• We have eliminated the introduction of a bullet and space at the start of some "numbered" paragraphs in .docx files, where Word itself does not show them.
• Treatment of blank cells in columnar tables has been amended to come more completely into compliance with BANA Guidelines.
• The BANA Listed Table format now conforms to BANA Formats 2011 (11.16.1.e), so that for each row, the first element is formatted as a cell-5 heading. (That first element is normally labeled with the column heading.)
• A Byte Order Mark, if present, is now stripped from the start of Unicode text imports, particularly when imported through DBT's formatted text importer.
• DBT now adds codes to control spacing within the Exact Translation style when importing Word .doc and .docx files.

DBT 12.1 SR1
2016-09-01 (2016-09-16)

Primary Improvements

• In all UEB templates as well as those derived from UEB, the computer braille styles are updated to render accurate word breaking. Only those templates specifically for older (pre-UEB) documents still enforce the Pre-UEB word breaking rules.
• The four DBT BANA templates (both UEB and Pre-UEB) are once again updated to the most recent versions. This corrects some formatting errors in the 12.1 BANA templates and includes BB-BoxBegin and H1-HeadingCentered.
• In the English/American (pre-UEB) print-to-braille tables, the output of underline symbols is restored.
• In the English/Unified (UEB) print-to-braille table certain contractions that follow an apostrophe have been improved.
• The Afrikaans print-to-braille table and Sotho print-to-braille table have been updated with contraction changes received recently from South Africa.
• Refinements in the Welsh print-to-braille table restrict shortform usage within large words to the officially approved list and ensure that strings of letters that could be read as extended shortforms are appropriately marked with grade 1 indicators. Other improvements include automated generation of hyphenation points within long technical expressions such as URLs.
• For Myanmar text, DBT now handles some additional, critical Burmese characters for translating Burmese text to braille.

---

DBT 12.1
2016-07-26 (2016-08-09)

Primary Areas of Improvement

• Many updates to DBT code and translation tables, including UEB.
• *.dxp (print) and *.dxb (braille) files are now interchangeable between DBT for Windows and DBT for Mac version 12.1
• The Basic DBT Templates have been streamlined (see below)
• New embossers and embosser fixes (see below)
• Math improvements (see below)
• 62 step UEB Mangold Method learning series now included in the Learning tables (Click here)
• Infrastructure changes to fix numerous issues with language switching and the translated line display in DBT
• Language improvements (see below)

DBT Templates Streamlined

• Historical DBT styles that no longer have effect have been removed
• Each Basic Template now has ten DBT styles that use language switching:
  • Biblical_lang (Biblical original language studies)
  • English_UEB1 (UEB grade 1)
  • English_UEB2 (UEB grade 2)
  • English_UK_old (British pre-UEB)
  • French
  • German
  • IPA
  • Italian
  • Russian
  • Spanish
• Italic, bold, and underline styles are now included in every basic language template
• Improved Russian formatting using a new Word style mapping file, rus.mws
• Better Australian formatting using a new Word style mapping file, aussie.mws, for UEB braille

Embossers

• New Embossers supported:
  • ViewPlus Columbia
  • Enabling Juliet 120
  • Enabling Romeo 60
  • Index V5 embossers
• Embosser fixes:
  • TactileView improved graphics support
  • Nippon Telesoft Gemini Super2 has been renamed as the Nippon Telesoft DOG-Pro
  • Nippon Telesoft DOG-Pro carriage width calculations are more accurate

Mathematics

Numerous additions to math functionality; here are the highlights:

• Many more unusual mathematics characters are now handled
• Spacing and control of spacing around function names in UEB math and French math have been improved
• Better importing of aligned structures
• Better handling of the Unicode minus sign
• Nemeth translation has been updated to use dot 6 for the comma when outside of "technical notation" but still in "Nemeth mode." This means that in the English (UEB) - BANA with Nemeth template, a comma in the style math-TextInMath is brailled as dot 6, rather than dots 456,2 following Nemeth rules.

UEB Updates

• When translating material into UEB, the translator is more selective about switching to a grade one passage for technical notation
• Improved auto-hyphenation, including grouping of braille numbers 16 cells or less in length
• Symbols that are not hyphens nor dashes, but contain dots 36, are no longer allowed as potential line break points
• The translation of certain unusual names has been fixed
• The translation of mixed alpha-numerics, such as AA.12, has been adjusted to be easier to read in braille
• Mid-line ellipsis (U+22EF), double or triple dots over a variable name, and other uncommon math symbols, are now treated correctly

• Braille-to-print support for Old/Middle English letters: yogh, thorn, eth and wynn
• Plus many other changes to improve the production of UEB braille

Restored Functionality

• Restoration of the francais.mws Word style map file
• Repair of the Hindi file importer
