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. See

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

to find out why it is implemented that way.
