.SH DESCRIPTION
.IX Header "DESCRIPTION"
To find out how to use this module in detail, see Encode.
.SH "Note on ISO\-2022\-JP(\-1)?"
.IX Header "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.
.PP
.Vb 1
\& $utf8 = decode(\*(Aqiso\-2022\-jp\-1\*(Aq, $stream);
.Ve
.PP
and
.PP
.Vb 1
\& $utf8 = decode(\*(Aqiso\-2022\-jp\*(Aq, $stream);
.Ve
.PP
yield the same result but
.PP
.Vb 1
\& $with_0212 = encode(\*(Aqiso\-2022\-jp\-1\*(Aq, $utf8);
.Ve
.PP
is now different from
.PP
.Vb 1
\& $without_0212 = encode(\*(Aqiso\-2022\-jp\*(Aq, $utf8 );
.Ve
.PP
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.
.SH BUGS
.IX Header "BUGS"
The ASCII region (0x00\-0x7f) is preserved for all encodings, even
though this conflicts with mappings by the Unicode Consortium.
