6 # This file is a supplement to the UnicodeData file.
7 # It contains additional information about the casing of Unicode characters.
8 # (For compatibility, the UnicodeData.txt file only contains case mappings for
9 # characters where they are 1-1, and does not have locale-specific mappings.)
10 # For more information, see the discussion of Case Mappings in the Unicode Standard.
12 # All code points not listed in this file that do not have a simple case mappings
13 # in UnicodeData.txt map to themselves.

17 # The entries in this file are in the following machine-readable format:
19 # <code>; <lower> ; <title> ; <upper> ; (<condition_list> ;)? # <comment>
21 # <code>, <lower>, <title>, and <upper> provide character values in hex. If there is more than
22 # one character, they are separated by spaces. Other than as used to separate elements,
23 # spaces are to be ignored.
25 # The <condition_list> is optional. Where present, it consists of one or more locales or contexts,
26 # separated by spaces. In these conditions:
27 # - A condition list overrides the normal behavior if all of the listed conditions are true.
28 # - The context is always the context of the characters in the original string,
29 # NOT in the resulting string.
30 # - Case distinctions in the condition list are not significant.
31 # - Conditions preceded by "Not_" represent the negation of the condition.
33 # A locale is defined as:
34 # <locale> := <ISO_639_code> ( "_" <ISO_3166_code> ( "_" <variant> )? )?
35 # <ISO_3166_code> := 2-letter ISO country code,
36 # <ISO_639_code> := 2-letter ISO language code
38 # A context is one of the following, as defined in the Unicode Standard:
39 # Final_Sigma, After_Soft_Dotted, More_Above, Before_Dot, Not_Before_Dot, After_I
41 # Parsers of this file must be prepared to deal with future additions to this format:
