# BidiMirroring-1.txt
# 
# This file is an informative supplement to the UnicodeData file. It
# lists characters that have the mirrored property
# where there is another Unicode character that typically has a glyph
# that is the mirror image of the original character's glyph.
# The repertoire covered by the file is Unicode 3.0.1.
# 
# The file contains a list of lines with mappings from one code point
# to another one for character-based mirroring.
# Note that for "real" mirroring, a rendering engine needs to select
# appropriate alternative glyphs, and that many Unicode characters do not
# have a mirror-image Unicode character.
# 
# Each mapping line contains two fields, separated by a semicolon (';').
# Each of the two fields contains a code point represented as a
# variable-length hexadecimal value with 4 to 6 digits.
# A comment indicates where the characters are "BEST FIT" mirroring.
# 
# Code points with the "mirrored" property but no appropriate mirrors are
# listed as comments at the end of the file.
# 
# For information on bidi mirroring, see UTR #21: Bidirectional Algorithm,
# at http://www.unicode.org/unicode/reports/tr9/
# 
# Please address any comments to <errata@unicode.org>.
# Note that this is an archival address: messages will be checked,
# but do not expect an immediate response.
