VIETNAMESE (Uncontracted) Vietname Flag

Functional Summary

The Vietnamese tables support print-to-braille translation of Vietnamese-language literary text in grade 1. Mathematics according to the English/Unified Braille (UEB) code is also supported; however, since this code is not officially approved for general use in Vietnam at this writing (April 2004), use of this table for such material should be limited to experimental purposes only.

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: Please be sure to include sample files!

Special Requirements and Limitations

True braille-to-print translation is not supported. This means that a braille file will not translate correctly to print. It also means that the "translated line" will typically contain gibberish when working in a braille file.

Secondary Languages Supported

No secondary languages are supported.

Technical Braille Codes Supported

UEBC incorporates technical notation such as for mathematics, science and computer material. The method for entering mathematics and other technical notation is the same as for the technical codes supported in the English/American and English/British tables.

Supported DBT Translation Codes

(Supported codes are substantially similar to those listed for the English/Unified tables. At present, the exact list is not complete as these tables are at an experimental stage of development.)

Characters Supported

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

All ASCII printable characters

Tone marks and accents appropriate for Vietnamese language text.

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. (in "technical context," i.e. Nemeth Code, only) (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).

References, History and Credits

The earliest versions of this table were developed by Duxbury Systems in December 1993, working with the Blind Citizens of Australia, primarily on behalf of a school for the blind near Hanoi. In April 2001, that early table was revised by Duxbury Systems for use in the next release of the Windows version of DBT, and the UEBC math treatment was added experimentally. The latter work is ongoing, in conjunction with colleagues in Hanoi and Ho Chi Minh City, Viet Nam.
