=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().
