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

60 =head1 Note on ISO-2022-JP(-1)?
62 ISO-2022-JP-1 (RFC2237) is a superset of ISO-2022-JP (RFC1468) which
63 adds support for JIS X 0212-1990. That means you can use the same
64 code to decode to utf8 but not vice versa.
66 $utf8 = decode('iso-2022-jp-1', $stream);
70 $utf8 = decode('iso-2022-jp', $stream);
72 yield the same result but
74 $with_0212 = encode('iso-2022-jp-1', $utf8);
78 $without_0212 = encode('iso-2022-jp', $utf8 );
80 In the latter case, characters that map to 0212 are first converted
81 to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu' or
82 'geta mark') then fed to the decoding engine. U+FFFD is not used,
83 in order to preserve text layout as much as possible.
87 The ASCII region (0x00-0x7f) is preserved for all encodings, even
88 though this conflicts with mappings by the Unicode Consortium. See
90 L<http://www.debian.or.jp/~kubota/unicode-symbols.html.en>
92 to find out why it is implemented that way.
