=head1 NAME
PerlIO::encoding - encoding layer
=head1 SYNOPSIS
use PerlIO::encoding;
open($f, "<:encoding(foo)", "infoo");
open($f, ">:encoding(bar)", "outbar");
use Encode qw(:fallbacks);
$PerlIO::encoding::fallback = FB_PERLQQ;
=head1 DESCRIPTION
This PerlIO layer opens a filehandle with a transparent encoding filter.
On input, it converts the bytes expected to be in the specified
character set and encoding to Perl string data (Unicode and
Perl's internal Unicode encoding, UTF-8). On output, it converts
Perl string data into the specified character set and encoding.
When the layer is pushed, the current value of C<$PerlIO::encoding::fallback>
is saved and used as the CHECK argument when calling the Encode methods
encode() and decode().
