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.

	 Canonical   Alias	       Description
	 --------------------------------------------------------------------
	 euc-jp	     /\beuc.*jp$/i     EUC (Extended Unix Character)
		     /\bjp.*euc/i
		 /\bujis$/i
	 shiftjis    /\bshift.*jis$/i  Shift JIS (aka MS Kanji)
		 /\bsjis$/i
	 7bit-jis    /\bjis$/i	       7bit JIS
	 iso-2022-jp		       ISO-2022-JP		    [RFC1468]
		       = 7bit JIS with all Halfwidth Kana
			 converted to Fullwidth
	 iso-2022-jp-1		       ISO-2022-JP-1		    [RFC2237]
				       = ISO-2022-JP with JIS X 0212-1990
			 support.  See below
	 MacJapanese		       Shift JIS + Apple vendor mappings
	 cp932	     /\bwindows-31j$/i Code Page 932
				       = Shift JIS + MS/IBM vendor mappings
	 jis0201-raw		       JIS0201, raw format
	 jis0208-raw		       JIS0201, raw format
	 jis0212-raw		       JIS0201, raw format

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.  See

       <http://www.debian.or.jp/~kubota/unicode-symbols.html.en>

       to find out why it is implemented that way.
