On input, it converts the bytes expected to be in the specified character set and encoding to Perl string data (Unicode and Perl's internal Unicode encoding, UTF-8). On output, it converts Perl string data into the specified character set and encoding. When the layer is pushed, the current value of C<$PerlIO::encoding::fallback> is saved and used as the CHECK argument when calling the Encode methods encode() and decode(). =head1 SEE ALSO L<open>, L<Encode>, L<perlfunc/binmode>, L<perluniintro> =cut SIMPAN PERUBAHAN
