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().
