Perl version 5.10.0 documentation - PerlIO::encoding

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().
