** Braille table improvements
- Remove computer braille from Japanese Kantenji as it is not part of
the standard. Thanks to Kensaku Yoza.
- Bring Swedish tables up to date with the latest standard published
by Punktskriftsnämnden (the Swedish Braille Authority) in 2009. The
table for uncontracted braille was replaced and new tables for
(partially and fully) contracted braille have been added. Thanks to
David Renström from Insyn Scandinavia AB.
- Improvements to Hungarian (added more exceptions) and migration to
the ~nonumsign~ opcode thanks to Attila Hammer.
- Fixed a bug in the Ukrainian table that led to wrong translation of
some uppercase letters. Thanks to Andrey Yakuboy and Bert Frees.
- Augment the UEB grade 2 tables to resolve an ambiguity between lower
groupsigns and punctuation at the beginning of words by placing a letter
sign at the front of punctuation. This resolves an ambiguity between, for
example, "discount" and ".count". Thanks to Krzysztof Drewniak.
- Add a new table for /Chinese Common Braille Scheme/ which is a type
of braille used for spelling Mandarin Chinese. It is a variant of
the /Chinese Current Braille System/ but has more perfect marking
rules and produces less ambiguity than the latter. For more
information see the comments in ~zhcn-cbs.ctb~. Thanks to Cary-Rowen
and Frank.
- Updates to the Chinese bopomofo braille table thanks to Bo-Cheng
