+# This file is a supplement to the UnicodeData file.
+# It contains additional information about the casing of Unicode characters.
+# (For compatibility, the UnicodeData.txt file only contains case mappings for
+# characters where they are 1-1, and does not have locale-specific mappings.)
+# For more information, see the discussion of Case Mappings 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 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 locale IDs
+# or contexts, separated by spaces. In these conditions:
+# - A condition list overrides the normal behavior if all of the listed conditions are true.
+# - The 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.
+#
+# A locale ID is defined by taking any language tag as defined by
+# RFC 3066 (or its successor), and replacing '-' by '_'.
+#
+# A context for a character C is defined by Section 3.13 Default Case 
+# Operations, of The Unicode Standard, Version 5.0.
+# (This is identical to the context defined by Unicode 4.1.0,
+#  as specified in http://www.unicode.org/versions/Unicode4.1.0/)
+#
+# 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>))
