=head1 DESCRIPTION
To find how to use this module in detail, see L<Encode>.
+=head1 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);
+ $utf8 = decode('iso-2022-jp', $stream);
+
+Yields 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 at first converted
+to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu') then
+fed to decoding engine. U+FFFD is not used to preserve text layout as
+much as possible.

=head1 BUGS
ASCII part (0x00-0x7f) is preserved for all encodings, even though it
conflicts with mappings by the Unicode Consortium. See
-F<http://www.debian.or.jp/~kubota/unicode-symbols.html.en>
+L<http://www.debian.or.jp/~kubota/unicode-symbols.html.en>
to find why it is implemented that way.
