NAME

6       Encode::JP - Japanese Encodings
7

SYNOPSIS

9           use Encode qw/encode decode/;
10           $euc_jp = encode("euc-jp", $utf8);   # loads Encode::JP implicitly
11           $utf8   = decode("euc-jp", $euc_jp); # ditto

ABSTRACT

14       This module implements Japanese charset encodings.  Encodings supported
15       are as follows.

Note on ISO-2022-JP(-1)?

43       ISO-2022-JP-1 (RFC2237) is a superset of ISO-2022-JP (RFC1468) which
44       adds support for JIS X 0212-1990.  That means you can use the same code
45       to decode to utf8 but not vice versa.
46
47         $utf8 = decode('iso-2022-jp-1', $stream);
48
49       and
50
51         $utf8 = decode('iso-2022-jp',   $stream);
52
53       yield the same result but
54
55         $with_0212 = encode('iso-2022-jp-1', $utf8);
56
57       is now different from
58
59         $without_0212 = encode('iso-2022-jp', $utf8 );
60
61       In the latter case, characters that map to 0212 are first converted to
62       U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu' or 'geta
63       mark') then fed to the decoding engine.  U+FFFD is not used, in order
64       to preserve text layout as much as possible.
65

BUGS

67       The ASCII region (0x00-0x7f) is preserved for all encodings, even
68       though this conflicts with mappings by the Unicode Consortium.  See
69
70       <http://www.debian.or.jp/~kubota/unicode-symbols.html.en>
71
72       to find out why it is implemented that way.
