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).

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.
