(The initial translation table for a translation is determined by the selected template, and may be changed using the Document / Translation Tables menu. Using those menus does not involve explicit use of the table designator. However, in cases where it is necessary to switch to a different translation table partway through a file, the designator for the table being switched to is required; see the general description of the [lnb~...] command for further details.)
The Afrikaans tables support print-to-braille translation of Afrikaans-language literary text, in either grade 2 (contracted) or grade 1 (uncontracted) braille, according to the Unified Afrikaans Braille standard developed circa 2007-2010.
Braille-to-print translation is supported for this language. However Braille-to-print translation may not be perfect, therefore errors could occur. If you find any errors, or have suggestions, please send both the *.dxb and *.dxp files along with an explanation to: languages@duxsys.com (Please be sure to include sample files).
There are no special requirements or limitations.
Several other languages may be entered and treated in grade 1 "Afrikaans context", using the [lng...] code to switch. For instance, [lng~fr] (or [lng~fra]) would introduce a French passage to be treated as French grade 1 for the letters and accented letters (but with Afrikaans punctuation and indicators). That passage would be terminated, i.e. reverting to Afrikaans, at [lng] (or [lng~af] or [lng~afr]). The available languages, together with their associated "lng" codes, are:
de (or deu) -- German
en (or eng) -- English
es (or esp) -- Spanish
fi -- Finnish
fr (or fra) -- French
it (or ita) -- Italian
la (or lat) -- Latin
nl -- Dutch
pt -- Portuguese
sv -- Swedish
sw -- Swahili
Note that in addition to the above-listed "secondary languages" supported within the Afrikaans table itself, it is also possible to switch to any of the available translation tables listed in DBT. (See the [lnb~...] code below.)
No separate technical braille codes are supported. Unified Afrikaans itself incorporates technical notation such as for mathematics, science and computer material in a manner consistent with Unified English Braille (UEB), and so no separate technical code is needed for such material. The method for entering mathematics and other technical notation is the same as for UEB.
It is also possible to switch to any of the available translation tables listed in DBT (see the [lnb~...]code below), many of which do support various technical codes, such as for mathematics or computer notation, or which support “unified” treatment of technical notation as well as literary text in the base language associated with the table.
The following DBT translation codes are available when using the Afrikaans table. Any other translation codes used will be ignored, or indeed may cause unexpected results. If using an alternative translation table, i.e when switching to another base language table by means of the[lnb~...] code, please refer to the relevant topic and available codes for that table.

[tce] -- allowed but not needed (ignored).
[tcs] -- allowed but not needed (ignored).
[te] -- terminates the grade 1 passage initiated by [ts], inserting grade 1 passage termination indicator, if the prevailing mode is grade 2, and resumes the prevailing grade as established by [g1] or [g2].
[tne]
[tns]
[ts] initiates "technical notation," i.e. a "grade 1 passage," inserting the grade 1 passage indicator if the prevailing mode as established by [g1] or [g2] is grade 2, and establishes grade 1 translation.
[tx]
[u]
[uce](see [ucs])
[ucl0~"] establishes that the ordinary keyboard double quote (U+0022) is to be interpreted flexibly, i.e. as an opening quote or a closing quote according to the immediate context. This is the default (initial) condition.
[ucl1~"] establishes that the ordinary keyboard double quote (U+0022) is to be interpreted literally, i.e. as a nondirectional double quote, and translated as such.
[ucs] marks the beginning of a capital passage when it is desirable to override the automatic logic for determining capital passages. All letters between [ucs] ... [uce] pairs are treated as capitals regardless of their actual case.
[ue]
[ui]
[uoq] causes the prevailing quote marks to be "unset," which is the default (initial) condition. When the prevailing quote marks are unset, the first actual quote mark (of those listed above) next encountered in the file determines the prevailing quote mark for the rest of the file unless until a subsequent [uoq...] command is encountered.
[uoq~"] or [uoq~0022] sets the prevailing (or "outer") opening and closing quote to the ordinary keyboard double-quote ("), i.e. U+0022. (This command is incompatible with [ucl1~"], which causes that kind of quote to be treated as nondirectional.)
[uoq~`] or [uoq~0060] sets the prevailing opening and closing quote to the grave accent character (`), i.e. U+0060.
[uoq~«] or [uoq~00ab] sets the prevailing opening quote to the left-pointing double angle quotation mark («), i.e. U+00ab, and the prevailing closing quote to the corresponding right-pointing mark.
[uoq~»] or [uoq~00bb] sets the prevailing opening quote to the right-pointing double angle quotation mark (»), i.e. U+00bb, and the prevailing closing quote to the corresponding left-pointing mark.
Generally speaking, any need to use a [uoq...] command would be very rare, as the default behavior should establish the actual quote pattern (e.g. single outer, double inner, or vice versa) correctly and provide the correct treatment automatically.
[us]
[vrn] cancels the effect of [vrn~ida], restoring the default, formal, treatment of dashes and hyphens, e.g. any surrounding spaces are preserved in the braille.
[vrn~ida] establishes a mode wherein dashes are treated informally. Specifically, a space at either end of a dash is not preserved in the braille, and double hyphens and spaced single hyphens are treated as full dashes (i.e. em-dashes).
[xcs]
The table is designed to work with the following groups of characters:
All ASCII printable characters
Accented letters and punctuation marks typical of Afrikaans
Accented characters and punctuation marks typical of French, German, Italian, Spanish, and Portuguese
British pound, Japanese yen, Euro, and other miscellaneous signs (DUSCI pages D+ec..., D+ed..., D+ee..., D+f5...)
Mathematical signs, shapes, etc. (DUSCI pages D+df..., D+e2..., D+e5..., D+ef..., D+f0..., D+f1...)
The above is a general guide only (see "General Notes" section at the beginning of this document).
These tables were initially developed from January 2007 through June 2010 by Mr. Christo de Klerk with the assistance of Duxbury Systems, Inc.
