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. 27 # ================================================================================ 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 56 # ================================================================================ 57 58 # ================================================================================ 59 # Unconditional mappings 60 # ================================================================================ 61 62 # The German es-zed is special--the normal mapping is to SS. 63 # Note: the titlecase should never occur in practice.
