\& $PerlIO::encoding::fallback = FB_PERLQQ;
Open a filehandle with a transparent encoding filter.
On input, convert the bytes expected to be in the specified
character set and encoding to Perl string data (Unicode and
Perl's internal Unicode encoding, \s-1UTF\-8\s0). On output, convert
Perl string data into the specified character set and encoding.
When the layer is pushed the current value of \f(CW$PerlIO::encoding::fallback\fR
is saved and used as the \s-1CHECK\s0 argument when calling the Encode methods \fIencode()\fR
