Table Designator


This is the technical description of a DBT Translation table. If you want more general information about languages and template choices, please see the list of templates.

Initially, the language table for braille translation is determined by the selected template, and may be changed using the Document / Translation Tables menu. Using those menus does not require use of the table designator. However, to switch to a different translation table partway through a file, one must enter a DBT code and the designator for the table to switch to. For switching secondary languages within a base language table, see the [lng~X] command. For switching from one base language to another, see the [lnb~...] command.

Functional Summary

The Tibetan tables support print-to-braille translation of Tibetan-language literary text into uncontracted Tibetan braille.

Uncontracted English is also supported. Technical (mathematics and computer) notation is generally transcribed as in Unified English Braille (UEB).

Braille to Print (Back-translation)

Braille-to-print translation is supported for this language. However, braille-to-print translation may not be perfect, therefore beware that errors can occur. If you find 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!

Special Requirements and Limitations

Although DBT Win DBT 11.1 and later are able to display accented letter combinations and many non-Roman scripts, it is nevertheless often more convenient to use Microsoft Word for entering and editing print text, which can then be imported into DBT for subsequent translation. When preparing the text in Word, be sure to use a Unicode font (such as Lucida Sans or the default Times Roman), so that the underlying characters are encoded in Unicode. (Note that the appearance on screen is not the issue. Fonts that merely cause standard ASCII characters to be displayed as the desired accented or non-Roman letters will not work, because they will be imported according to their standard interpretation, not their appearance.)

Secondary Languages Supported

Roman script is generally transcribed as in Unified English Braille (UEB).

There are no secondary languages supported within the Tibetan table itself; however it is possible to switch to any of the available translation tables listed in DBT. (See the [lnb~...] code below.)

Technical Braille Codes Supported

Technical (mathematics, computer, or scientific) notation is generally transcribed as in Unified English Braille (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.

Supported DBT Translation Codes

The following DBT translation codes are available when using the Tibetan table. Codes related to the entry of type forms, mathematics, etc. as in the English/Unified tables may also be used and will generally be treated in the same way. 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.



[lnb~...] (for switching to another base [primary] language table)


Characters Supported

The table is designed to work with the following groups of characters:

All ASCII printable characters

Tibetan letters and punctuation marks

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 under the main “Language Translation Tables” topic).

References, History and Credits

The Tibetan Braille Translator is based on spreadsheets and pdf files provided by Braille Without Borders. Working with Braille Without Borders, we also included handling of the popular Wylie Romanization. We welcome comments to improve these tables.
