# Case Folding Properties
|
|
|
|
|
#
|
|
|
|
|
# This file is a supplement to the UnicodeData file.
|
|
|
|
|
# It provides a case folding mapping generated from the Unicode Character Database.
|
|
|
|
|
# If all characters are mapped according to the full mapping below, then
|
|
|
|
|
# case differences (according to UnicodeData.txt and SpecialCasing.txt)
|
|
|
|
|
# are eliminated.
|
|
|
|
|
#
|
|
|
|
|
# The data supports both implementations that require simple case foldings
|
|
|
|
|
# (where string lengths don't change), and implementations that allow full case folding
|
|
|
|
|
# (where string lengths may grow). Note that where they can be supported, the
|
|
|
|
|
# full case foldings are superior: for example, they allow "MASSE" and "Ma<4D>e" to match.
|
|
|
|
|
#
|
|
|
|
|
# NOTE: case folding does not preserve normalization formats!

# The entries in this file are in the following machine-readable format:
|
|
|
|
|
#
|
|
|
|
|
# <code>; <status>; <mapping>; # <name>
|
|
|
|
|
#
|
|
|
|
|
# The status field is:
|
|
|
|
|
# C: common case folding, common mappings shared by both simple and full mappings.
|
|
|
|
|
# F: full case folding, mappings that cause strings to grow in length. Multiple characters are separated by spaces.
|
|
|
|
|
# S: simple case folding, mappings to single characters where different from F.

|
# T: special case for uppercase I and dotted uppercase I
|
|
|
|
|
# - For non-Turkic languages, this mapping is normally not used.
|
|
|
|
|
# - For Turkic languages (tr, az), this mapping can be used instead of the normal mapping for these characters.

# Usage:
|

|
|
|
|
# A. To do a simple case folding, use the mappings with status C + S.
|
|
|
|
|
# B. To do a full case folding, use the mappings with status C + F.
|
|
|
|
|
#
|
|
|
|
|
# The mappings with status T can be used or omitted depending on the desired case-folding
|
|
|
|
|
# behavior. (The default option is to exclude them.)
