# Encode::JP(3perl)

Japanese Encodings

## 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.
