=head1 DESCRIPTION
-=cut
+Open a filehandle with a transparent encoding filter.
+On input, convert 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, convert
+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 Encodings
+encode and decode.
