These maps were generated by a perl script that comes with the module
XML::Encoding, compile_encoding, from XML formatted encoding maps that
are distributed with that module. These XML encoding maps were generated
in turn with a different script, domap, from mapping information contained
on the Unicode version 2.0 CD-ROM. This CD-ROM comes with the Unicode
Standard reference manual and can be ordered from the Unicode Consortium
at http://www.unicode.org. The identical information is available on the
internet at ftp://ftp.unicode.org/Public/MAPPINGS.
