#
# 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>))

# IMPORTANT-when iota-subscript (0345) is uppercased or titlecased,
#  the result will be incorrect unless the iota-subscript is moved to the end
#  of any sequence of combining marks. Otherwise, the accents will go on the capital iota.
#  This process can be achieved by first transforming the text to NFC before casing.
#  E.g. <alpha><iota_subscript><acute> is uppercased to <ALPHA><acute><IOTA>

# The following cases are already in the UnicodeData.txt file, so are only commented here.

# Turkish and Azeri

# I and i-dotless; I-dot and i are case pairs in Turkish and Azeri
# The following rules handle those cases.

0130; 0069; 0130; 0130; tr; # LATIN CAPITAL LETTER I WITH DOT ABOVE
0130; 0069; 0130; 0130; az; # LATIN CAPITAL LETTER I WITH DOT ABOVE

# When lowercasing, remove dot_above in the sequence I + dot_above, which will turn into i.
# This matches the behavior of the canonically equivalent I-dot_above

0307; ; 0307; 0307; tr After_I; # COMBINING DOT ABOVE
0307; ; 0307; 0307; az After_I; # COMBINING DOT ABOVE

# When lowercasing, unless an I is before a dot_above, it turns into a dotless i.

0049; 0131; 0049; 0049; tr Not_Before_Dot; # LATIN CAPITAL LETTER I
0049; 0131; 0049; 0049; az Not_Before_Dot; # LATIN CAPITAL LETTER I

# When uppercasing, i turns into a dotted capital I
