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. .SH "SEE ALSO" .IX Header "SEE ALSO" Encode
