Encodings supported are as follows.

ISO-2022-JP-1 (RFC2237) is a superset of ISO-2022-JP (RFC1468) which adds support for JIS X 0212-1990. That means you can use the same code to decode to utf8 but not vice versa. $utf8 = decode('iso-2022-jp-1', $stream); and $utf8 = decode('iso-2022-jp', $stream); yield the same result but $with_0212 = encode('iso-2022-jp-1', $utf8); is now different from $without_0212 = encode('iso-2022-jp', $utf8 ); In the latter case, characters that map to 0212 are first converted to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu' or 'geta mark') then fed to the decoding engine. U+FFFD is not used, in order to preserve text layout as much as possible. =head1 BUGS The ASCII region (0x00-0x7f) is preserved for all encodings, even though this conflicts with mappings by the Unicode Consortium. See L to find out why it is implemented that way. =head1 SEE ALSO L =cut
