PRI #202: Extensions to NameAliases.txt for Unicode 6.1.0
The UTC is planning to extend the format and content of the Unicode Character Database file NameAliases.txt for Unicode 6.1.0. In addition to the current scope of NameAliases.txt, which covers the definition of formal name aliases for characters whose names have serious mistakes in them, the intent is to add various standard and de facto aliases for control characters, which have no names defined for them in the Unicode Standard, as well as various character abbreviations which are in widespread use.
Details of the proposal and draft data file are available on the public review issue page: http://www.unicode.org/review/pri202/
