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

83 | =head1 BUGS |
84 | |
557e5ea9 |
85 | ASCII part (0x00-0x7f) is preserved for all encodings, even though it |
86 | conflicts with mappings by the Unicode Consortium. See |
87 | |
a63c962f |
88 | L<http://www.debian.or.jp/~kubota/unicode-symbols.html.en> |
557e5ea9 |
89 | |
90 | to find why it is implemented that way. |
