Further resources for the current international standard for French Braille,
adopted now in most francophone countries:
This is a necessary complement (finalized in 2006) to the recent adoption of
the standard mathematical Braille transcription system (adopted in last
November, published a few weeks ago, and mandatory for all publications
starting in next September).
I must cite them because it is easier to find resources about English
Braille (but there are several competing standards).
You'll find references for the standard 6-dot system, with complete
reference about how to codify not only characters, but also elements with
semantic importance like emphasizing, indices and exponents which are more
than just style. There are also important notes about the notation of
capitals, and the alternation of the base code and numeric code, as well as
the semantics of abbreviations.
The legacy 8-dot system for CP437 computing applications (1971) is also
described but deprecated, modified later to solve ambiguities between dots
and apostrophes and a few characters, and then modified in favour of a
CP1252-compatible encoding. This final version was made to give excellent
compatibility with the standard 6-dot system, so that the meaning of
characters with dots 7 or 8 can be guessed from 6-dot only characters, and
automated transcoding between 6-dot and 8-dot systems becomes possible
without creating confusion.
There remains space in the current 6-dot system for future extensions (such
extension is impossible with the 8-dot system, unless the few unused
positions in CP1252 (which are all bound to the same 6-dot pattern) are
given new meanings (and then mapped with a corresponding sequence of 6-dot
