59 | =head1 Note on ISO-2022-JP(-1)? |
| 60 | |
| 61 | ISO-2022-JP-1 (RFC2237) is a superset of ISO-2022-JP (RFC1468) which |
| 62 | adds support for JIS X 0212-1990. That means you can use the same |
| 63 | code to decode to utf8 but not vice versa. |
| 64 | |
| 65 | $utf8 = decode('iso-2022-jp-1', $stream); |
| 0ab8f81e |
66 | |
| 67 | and |
| 68 | |
| a63c962f |
69 | $utf8 = decode('iso-2022-jp', $stream); |
| 70 | |
| 0ab8f81e |
71 | yield the same result but |
| a63c962f |
72 | |
| 73 | $with_0212 = encode('iso-2022-jp-1', $utf8); |
| 74 | |
| 75 | is now different from |
| 76 | |
| 77 | $without_0212 = encode('iso-2022-jp', $utf8 ); |
| 78 | |
| 0ab8f81e |
79 | In the latter case, characters that map to 0212 are first converted |
| 80 | to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu' or |
| 81 | 'geta mark') then fed to the decoding engine. U+FFFD is not used, |
| 82 | in order to preserve text layout as much as possible. |

84 | =head1 BUGS |
| 85 | |
| 0ab8f81e |
86 | The ASCII region (0x00-0x7f) is preserved for all encodings, even |
| 87 | though this conflicts with mappings by the Unicode Consortium. See |
| 557e5ea9 |
