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().
