=head1 NAME

Encode::JP - Japanese Encodings

=head1 SYNOPSIS

    use Encode qw/encode decode/; 
    $euc_jp = encode("euc-jp", $utf8);   # loads Encode::JP implicitly
    $utf8   = decode("euc-jp", $euc_jp); # ditto

=head1 ABSTRACT

This module implements Japanese charset encodings.  Encodings
supported are as follows.

=head1 DESCRIPTION

To find how to use this module in detail, see L<Encode>.

=head1 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);

Yields 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 at first converted
to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu') then
fed to decoding engine.  U+FFFD is not used to preserve text layout as
much as possible.

=head1 BUGS

ASCII part (0x00-0x7f) is preserved for all encodings, even though it
conflicts with mappings by the Unicode Consortium.  See

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

to find why it is implemented that way.
