Encodings 33supported are as follows. 34 35 Canonical Alias Description 36 -------------------------------------------------------------------- 37 euc-jp /\beuc.*jp$/i EUC (Extended Unix Character) 38 /\bjp.*euc/i 39 /\bujis$/i 40 shiftjis /\bshift.*jis$/i Shift JIS (aka MS Kanji) 41 /\bsjis$/i 42 7bit-jis /\bjis$/i 7bit JIS 43 iso-2022-jp ISO-2022-JP [RFC1468] 44 = 7bit JIS with all Halfwidth Kana 45 converted to Fullwidth 46 iso-2022-jp-1 ISO-2022-JP-1 [RFC2237] 47 = ISO-2022-JP with JIS X 0212-1990 48 support.

That means you can use the same 65code to decode to utf8 but not vice versa. 66 67 $utf8 = decode('iso-2022-jp-1', $stream); 68 69and 70 71 $utf8 = decode('iso-2022-jp', $stream); 72 73yield the same result but 74 75 $with_0212 = encode('iso-2022-jp-1', $utf8); 76 77is now different from 78 79 $without_0212 = encode('iso-2022-jp', $utf8 ); 80 81In the latter case, characters that map to 0212 are first converted 82to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu' or 83'geta mark') then fed to the decoding engine. U+FFFD is not used, 84in order to preserve text layout as much as possible. 85 86=head1 BUGS 87 88The ASCII region (0x00-0x7f) is preserved for all encodings, even 89though this conflicts with mappings by the Unicode Consortium. 90 91=head1 SEE ALSO 92 93L<Encode> 94 95=cut 96
