C<no bytes> can be used to reverse +the effect of C<use bytes> within the current lexical scope. + +Perl normally assumes character semantics in the presence of +character data (i.e. data that has come from a source that has +been marked as being of a particular character encoding). + +To understand the implications and differences between character +semantics and byte semantics, see L<perlunicode>. + +=head1 SEE ALSO + +L<perlunicode>, L<utf8> + +=cut |
