## NAME
    [Encode::JP](https://www.chedong.com/phpMan.php/perldoc/Encode%3A%3AJP/markdown) - Japanese Encodings

## SYNOPSIS
        use Encode qw/encode decode/;
        $euc_jp = encode("euc-jp", $utf8);   # loads [Encode::JP](https://www.chedong.com/phpMan.php/perldoc/Encode%3A%3AJP/markdown) 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.
