NAME

       Encode::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.  Encodings 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 layout as much as possible.

BUGS

       The ASCII region (0x00-0x7f) is preserved for all encodings, even though this conflicts
       with mappings by the Unicode Consortium.
