       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.  Encod-
       ings supported are as follows.

         Canonical   Alias             Description
         euc-jp      /\beuc.*jp$/i     EUC (Extended Unix Character)
         shiftjis    /\bshift.*jis$/i  Shift JIS (aka MS Kanji)
         7bit-jis    /\bjis$/i         7bit JIS
         iso-2022-jp                   ISO-2022-JP                  [RFC1468]
                                       = 7bit JIS with all Halfwidth Kana
                                         converted to Fullwidth
         iso-2022-jp-1                 ISO-2022-JP-1                [RFC2237]
                                       = ISO-2022-JP with JIS X 0212-1990
                                         support.  See below

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);


         $utf8 = decode('iso-2022-jp',   $stream);

       yield the same result but

         $with_0212 = encode('iso-2022-jp-1', $utf8);

       is now different from

perl v5.8.5                 2002-11-06                          1

ext::Encode::JP::PerlpProgrammers Referencext::Encode::JP::JP(3p)

         $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 encod-
       ings, even though this conflicts with mappings by the Uni-
       code Consortium.  See


       to find out why it is implemented that way.
