=head1 Note on ISO-2022-JP(-1)? |
| 60 |
|
|
|
| 61 |
|
|
ISO-2022-JP-1 (RFC2237) is a superset of ISO-2022-JP (RFC1468) which |
| 62 |
|
|
adds support for JIS X 0212-1990. That means you can use the same |
| 63 |
|
|
code to decode to utf8 but not vice versa. |
| 64 |
|
|
|
| 65 |
|
|
$utf8 = decode('iso-2022-jp-1', $stream); |
| 66 |
|
|
|
| 67 |
|
|
and |
| 68 |
|
|
|
| 69 |
|
|
$utf8 = decode('iso-2022-jp', $stream); |
| 70 |
|
|
|
| 71 |
|
|
yield the same result but |
| 72 |
|
|
|
| 73 |
|
|
$with_0212 = encode('iso-2022-jp-1', $utf8); |
| 74 |
|
|
|
| 75 |
|
|
is now different from |
| 76 |
|
|
|
| 77 |
|
|
$without_0212 = encode('iso-2022-jp', $utf8 ); |
| 78 |
|
|
|
| 79 |
|
|
In the latter case, characters that map to 0212 are first converted |
| 80 |
|
|
to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu' or |
| 81 |
|
|
'geta mark') then fed to the decoding engine. U+FFFD is not used, |
| 82 |
|
|
in order to preserve text layout as much as possible. |

|
=head1 BUGS |
| 85 |
|
|
|
| 86 |
|
|
The ASCII region (0x00-0x7f) is preserved for all encodings, even |
| 87 |
|
|
though this conflicts with mappings by the Unicode Consortium. See |
| 88 |

|
