# Special Casing Properties # # This file is a supplement to the UnicodeData file. # It contains additional information about the casing of Unicode characters. # (For compatibility, the UnicodeData.txt file only contains case mappings for # characters where they are 1-1, and does not have locale-specific mappings.) # For more information, see the discussion of Case Mappings in the Unicode Standard. # # All code points not listed in this file that do not have a simple case mappings # in UnicodeData.txt map to themselves. # ================================================================================ # Format # ================================================================================ # The entries in this file are in the following machine-readable format: # # ; ; ; <upper> ; (<condition_list> ;)? # <comment> # # <code>, <lower>, <title>, and <upper> provide character values in hex. If there is more # than one character, they are separated by spaces. Other than as used to separate # elements, spaces are to be ignored. # # The <condition_list> is optional. Where present, it consists of one or more locale IDs # or contexts, separated by spaces. In these conditions: # - A condition list overrides the normal behavior if all of the listed conditions are true. # - The context is always the context of the characters in the original string, # NOT in the resulting string. # - Case distinctions in the condition list are not significant. # - Conditions preceded by "Not_" represent the negation of the condition. # # A locale ID is defined by taking any language tag as defined by # RFC 3066 (or its successor), and replacing '-' by '_'. # # A context for a character C is defined by Section 3.13 Default Case Operations, # on p. 89-90 of The Unicode Standard, Version 4.0, as amended by Unicode 4.0.1. # # Parsers of this file must be prepared to deal with future additions to this format: # * Additional contexts # * Additional fields # ================================================================================ # ================================================================================ # Unconditional mappings # ================================================================================
