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<http://www.debian.or.jp/~kubota/unicode-symbols.html.en> + +to find out why it is implemented that way. + +=head1 SEE ALSO + +L<Encode> + +=cut |
