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.
The Polish tables support print-to-braille translation of Polish-language literary text in contracted or uncontracted Polish braille. English text may also be processed as a sub-language, and converted to contracted or uncontracted English braille (following British conventions). The American Computer Braille Code (CBC) is also supported.
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: email@example.com. Please be sure to include sample files!
There are no special requirements or limitations.
English text may be entered as a secondary language, and converted to contracted or uncontracted English braille. That is, the grade switches affect the translation of the English text as well as the Polish text. In English literary text, British conventions are generally followed, to the extent that they sometimes differ slightly from American ones.
Note that in addition to the abovementioned treatment of English as a "secondary language" within the Polish table itself, it is also possible to switch to any of the available translation tables listed in DBT. (See the [lnb~...] code below.)
Computer Braille Code (CBC), as defined by the Braille Authority of North America, is supported.
In addition, it is 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 Polish 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.
[/] may be embedded within letter-groups that would normally be contracted, to prevent the contraction.
[ab] is equivalent to [g2]
[cz] switches to "direct braille," wherein braille is directly represented using the North American ASCII-braille code. (This is sometimes called "no-translate" or "computer grade 0")
[g1] switches to "grade 1" (uncontracted) braille. This affects the Polish text, and also any embedded English text.
[g2] switches to "grade 2" (contracted) braille. This is the normal mode, and to any embedded English text as well as the Polish text.
[in] is equivalent to [g1]
[lnb~...] (for switching to another base [primary] language table)
[lng~en] switches to English language.
[lng~pl] or [lng] switches to Polish language.
[tx] resumes normal translation, ending "direct braille."
The table is designed to work with the following groups of characters:
All ASCII printable characters
Accented letters and punctuation marks typical of French, German, Italian, Spanish and Polish
British pound sign (£)
The above is a general guide only (see "General Notes" section at the beginning of this document).
With some initial help from Duxbury Systems in October 1999, these tables have been developed by Zbigniew Drzazga of the University of Warsaw.
