# SpecialCasing-9.0.0.txt # Date: 2016-03-02, 18:55:13 GMT # © 2016 Unicode®, Inc. # Unicode and the Unicode Logo are registered trademarks of Unicode, Inc. in the U.S. and other countries. # For terms of use, see http://www.unicode.org/terms_of_use.html # # Unicode Character Database # For documentation, see http://www.unicode.org/reports/tr44/ # # Special Casing # # This file is a supplement to the UnicodeData.txt file. It does not define any # properties, but rather provides additional information about the casing of # Unicode characters, for situations when casing incurs a change in string length # or is dependent on context or locale. For compatibility, the UnicodeData.txt # file only contains simple case mappings for characters where they are one-to-one # and independent of context and language. The data in this file, combined with # the simple case mappings in UnicodeData.txt, defines the full case mappings # Lowercase_Mapping (lc), Titlecase_Mapping (tc), and Uppercase_Mapping (uc). # # Note that the preferred mechanism for defining tailored casing operations is # the Unicode Common Locale Data Repository (CLDR). For more information, see the # discussion of case mappings and case algorithms 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: # # <code>; <lower>; <title>; <upper>; (<condition_list>;)? # <comment> # # <code>, <lower>, <title>, and <upper> provide the respective full case mappings # of <code>, expressed as 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 language IDs # or casing contexts, separated by spaces. In these conditions: # - A condition list overrides the normal behavior if all of the listed conditions are true. # - The casing 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. # The condition list is not represented in the UCD as a formal property. # # A language ID is defined by BCP 47, with '-' and '_' treated equivalently. # # A casing context for a character is defined by Section 3.13 Default Case Algorithms # of The Unicode Standard. # # Parsers of this file must be prepared to deal with future additions to this format: # * Additional contexts # * Additional fields # ================================================================================ # ================================================================================ # Unconditional mappings # ================================================================================ # The German es-zed is special--the normal mapping is to SS. # Note: the titlecase should never occur in practice. It is equal to titlecase(uppercase(<es-zed>)) 00DF; 00DF; 0053 0073; 0053 0053; # LATIN SMALL LETTER SHARP S # Preserve canonical equivalence for I with dot.
