| 30 | |
| 31 | This module implements Japanese charset encodings. Encodings |
| 32 | supported are as follows. |

56 | =head1 Note on ISO-2022-JP(-1)? |
| 57 | |
| 58 | ISO-2022-JP-1 (RFC2237) is a superset of ISO-2022-JP (RFC1468) which |
| 59 | adds support for JIS X 0212-1990. That means you can use the same |
| 60 | code to decode to utf8 but not vice versa. |
| 61 | |
| 62 | $utf8 = decode('iso-2022-jp-1', $stream); |
| 63 | $utf8 = decode('iso-2022-jp', $stream); |
| 64 | |
| 65 | Yields the same result but |
| 66 | |
| 67 | $with_0212 = encode('iso-2022-jp-1', $utf8); |
| 68 | |
| 69 | is now different from |
| 70 | |
| 71 | $without_0212 = encode('iso-2022-jp', $utf8 ); |
| 72 | |
| 73 | In the latter case, characters that map to 0212 are at first converted |
| 74 | to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu') then |
| 75 | fed to decoding engine. U+FFFD is not used to preserve text layout as |
| 76 | much as possible. |

78 | =head1 BUGS |
| 79 | |
| 557e5ea9 |
80 | ASCII part (0x00-0x7f) is preserved for all encodings, even though it |
| 81 | conflicts with mappings by the Unicode Consortium. See |
| 82 | |
| a63c962f |
83 | L<http://www.debian.or.jp/~kubota/unicode-symbols.html.en> |
| 557e5ea9 |
84 | |
| 85 | to find why it is implemented that way. |
