Updates to the UEB Rulebook

The following updates to the UEB Rulebook (2013) have been approved, taking effect immediately, and will be included in the next edition of the UEB Rulebook. Transcribers and designers of braille translation software and equipment are asked to implement these changes now.

7.6.5 single quotation mark or apostrophe
(Change as of August 4, 2015)

An amendment to the wording of section 7.6.5 has been approved, as follows (with added words in italics). Further changes to the rules for the apostrophe and quotation marks are still under consideration.

7.6.5 Use one-cell (nonspecific) quotation marks when apostrophes are used as the predominant quotation marks in print. Use specific single quotation marks when apostrophes are used as the secondary or inner quotation marks in print. However, when in doubt as to whether a mark is an apostrophe or a single quotation mark, treat it as an apostrophe when between letters, and as a single quotation mark in other circumstances.

10.12.2 Error in brailling of example
(Change as of March 15, 2017)

The lower groupsign for "ea" is not used in the word "reactor".

Strong contractions; See Section 10.3:

CANDU reactor ⠠⠠⠉⠯⠥⠀⠗⠑⠁⠉⠞⠕⠗
[Canada Deuterium Uranium]

Appendix 1: Shortforms List
(Change as of March 26, 2015)

Under "paid", the word unrepaid has been added to the List.

Under "said" the word unsaid has been added to the List.

Guidelines for Technical Material

This guidelines document has been produced by the Maths Focus Group, a subgroup of the former UEB Rules Committee during the UEB development phase. The purpose of this document is to give transcribers enough information and examples to produce Mathematics, Science and Computer notation in Unified English Braille.

In August 2014, a new version was produced to correct errors in the October 2008 edition. This version is available in print or braille:
Guidelines for Technical Material 2014 (PDF format)
Guidelines for Technical Material 2014 (BRF [formatted braille] format)

For those who already have copies of the October 2008 edition, errata are available in print (5 pages) and braille (7 pages):
Errata GTM 2014 (pdf format)
Errata GTM 2014 (brf [formatted braille] format)

UEB History

In April 2004, the ICEB General Assembly declared Unified English Braille to be substantially complete and that it could be recognized as an international standard and considered for adoption by individual countries. The original UEBC Research Project and its subcommittees were disbanded and replaced by a new project charged with oversight over UEB, including its further development.

Subsequently, after official adoption in five countries, the ICEB Executive, at its July 2010 meeting, determined that the development phase was complete and replaced the development project with a UEB Maintenance Committee.

Some of the documents pertinent to the research phase of the project, as listed in UEBC Research Project Information -- especially the final committee reports presented at the 2004 General Assembly -- are useful as background information as to how UEB was developed and why certain decisions were made. However, the documents listed on this page provide the most up-to-date information about UEB and in particular, the Rulebook should be considered definitive.

UEB training and resource materials

ICEB has compiled a list of UEB training and resouce materials available for free from its member countries.
