Global: Internationalization

Keystroke: Select from menu

Changing the language of your user interface is powerful, but it can be a little daunting. That is why the last section in this topic explains how to recover if you find yourself inadvertently facing a language that you cannot read.

Language for Menus and Dialogs

Subject to its availability in the list, you may now select a different language for the DBT user interface. If you select Dansk for example, all your menus and dialogs will appear in Danish.

In some instances, you may need to perform additional tasks to set up DBT for your own country or locale. Your local dealer is best placed to advise you on those requirements.

Braille Encoding for Input and Display

A braille encoding is not related to the current braille translator being used. A braille encoding is a direct one-to-one correspondence between individual braille cells and the computer characters used to represent them. This set of corresponding character-codes and dot patterns enables constructing braille fonts and displaying braille on a screen.

In North America, the normal braille encoding is called North American. For American braille users it would be difficult to imagine a reason to change this, except to provide technical support for users outside of North America.

For a user in Germany, on the other hand, the likely need is to handle German braille documents, to have those documents appear correctly on the screen, and to have a connected refreshable braille display produce the correct braille dot patterns. This requires using the German braille encoding. Again, this “encoding” is a standard correspondence between a braille dot pattern and the computer character used to represent it.

As another example, when DBT displays braille dot patterns on its own screen, the way this is done is usually not an issue to a user. But if the user is blind and is using software like JAWS to drive a braille device to follow the screen, then it becomes critical that the braille on the screen match the braille on the braille display. This is only possible if the braille font the program uses matches the braille encoding used on the braille display device.

DBT sends ASCII characters to drive braille devices. Around the world, different devices and different regions may use different systems (encodings) to associate those ASCII characters with braille dot patterns. This is an area that is quite technical, and it is frustrating if it is not set up properly. However, virtually all braille devices can work with the North American system, which is the default choice. Or you can select another system in this section of the Internationalization dialog to make the program match the device's encoding.

Note: When you make a change in this option, you need to close and then re-launch the program to have the change take effect. As DBT starts up, it constructs the braille font for its own use based on the setting of this menu item. This only happens at start-up.

DBT uses a file called display.cpt to link braille symbols with ASCII characters. To solve problems that cannot be handled using the existing Internationalization choices, this table can be edited directly. However, please, do not ever rearrange items in this file. DBT remembers settings based on their order in this list.

Again, should you change the Braille code for display, you will need to restart DBT for the change to take effect. You will also receive a warning dialog that the display will be incorrect until you restart the program.
