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().
