+=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().
