ext::Encode::JP::PerlpProgrammers Referencext::Encode::JP::JP(3p)NAMEEncode::JP - Japanese Encodings
SYNOPSIS
use Encode qw/encode decode/;
$euc_jp = encode("euc-jp", $utf8); # loads Encode::JP implicitly
$utf8 = decode("euc-jp", $euc_jp); # ditto
ABSTRACT
This module implements Japanese charset encodings. Encod-
ings supported are as follows.

DESCRIPTION
To find out how to use this module in detail, see Encode.
Note on ISO-2022-JP(-1)?
ISO-2022-JP-1 (RFC2237) is a superset of ISO-2022-JP
(RFC1468) which adds support for JIS X 0212-1990. That
means you can use the same code to decode to utf8 but not
vice versa.
$utf8 = decode('iso-2022-jp-1', $stream);
and
$utf8 = decode('iso-2022-jp', $stream);
yield the same result but

$with_0212 = encode('iso-2022-jp-1', $utf8);
is now different from
$without_0212 = encode('iso-2022-jp', $utf8 );
In the latter case, characters that map to 0212 are first
converted to U+3013 (0xA2AE in EUC-JP; a white square also
known as 'Tofu' or 'geta mark') then fed to the decoding
engine. U+FFFD is not used, in order to preserve text lay-
out as much as possible.
BUGS
The ASCII region (0x00-0x7f) is preserved for all encodings,
even though this conflicts with mappings by the Unicode Con-
sortium. See
<http://www.debian.or.jp/~kubota/unicode-symbols.html.en>
to find out why it is implemented that way.
