Encode::JP - Japanese Encodings
use Encode qw/encode decode/; $euc_jp = encode("euc-jp", $utf8); # loads Encode::JP implicitly $utf8 = decode("euc-jp", $euc_jp); # ditto
This module implements Japanese charset encodings. Encodings supported are as follows.

To find out how to use this module in detail, see Encode.
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 layout as much as possible.
The ASCII region (0x00-0x7f) is preserved for all encodings, even though this conflicts with mappings by the Unicode Consortium.
