10 # Special Casing
11 #
12 # This file is a supplement to the UnicodeData.txt file. It does not define any
13 # properties, but rather provides additional information about the casing of
14 # Unicode characters, for situations when casing incurs a change in string length
15 # or is dependent on context or locale. For compatibility, the UnicodeData.txt
16 # file only contains simple case mappings for characters where they are one-to-one
17 # and independent of context and language. The data in this file, combined with
18 # the simple case mappings in UnicodeData.txt, defines the full case mappings
19 # Lowercase_Mapping (lc), Titlecase_Mapping (tc), and Uppercase_Mapping (uc).
20 #
21 # Note that the preferred mechanism for defining tailored casing operations is
22 # the Unicode Common Locale Data Repository (CLDR). For more information, see the
23 # discussion of case mappings and case algorithms in the Unicode Standard.
24 #
25 # All code points not listed in this file that do not have a simple case mappings
26 # in UnicodeData.txt map to themselves.

28 # Format
29 # ================================================================================
30 # The entries in this file are in the following machine-readable format:
31 #
32 # <code>; <lower>; <title>; <upper>; (<condition_list>;)? # <comment>
33 #
34 # <code>, <lower>, <title>, and <upper> provide the respective full case mappings
35 # of <code>, expressed as character values in hex. If there is more than one character,
36 # they are separated by spaces. Other than as used to separate elements, spaces are
37 # to be ignored.
38 #
39 # The <condition_list> is optional. Where present, it consists of one or more language IDs
40 # or casing contexts, separated by spaces. In these conditions:
41 # - A condition list overrides the normal behavior if all of the listed conditions are true.
42 # - The casing context is always the context of the characters in the original string,
43 # NOT in the resulting string.
44 # - Case distinctions in the condition list are not significant.
45 # - Conditions preceded by "Not_" represent the negation of the condition.
46 # The condition list is not represented in the UCD as a formal property.
47 #
48 # A language ID is defined by BCP 47, with '-' and '_' treated equivalently.
49 #
50 # A casing context for a character is defined by Section 3.13 Default Case Algorithms
51 # of The Unicode Standard.
52 #
53 # Parsers of this file must be prepared to deal with future additions to this format:
54 # * Additional contexts
55 # * Additional fields
