Some of maps were "hand tweaked" from the output of the script, for
example utf8_to_sjis.map. See git log for more details. This is due to
part of the source file was not incomplete or inappropriate. Also we
needed to compromise while creating a mapping between some local
encodings (for example SJIS) and Unicode, because in the source
mapping file round trip conversion is not guaranteed.
