NAME
       PerlIO::encoding - encoding layer
SYNOPSIS
         use PerlIO::encoding;
         open($f, "<:encoding(foo)", "infoo");
         open($f, ">:encoding(bar)", "outbar");
         use Encode qw(:fallbacks);
         $PerlIO::encoding::fallback = FB_PERLQQ;
DESCRIPTION
       This PerlIO layer opens a filehandle with a transparent encoding
       filter.
       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
       $PerlIO::encoding::fallback is saved and used as the CHECK argument
       when calling the Encode methods encode() and decode().
