|
|
|
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().
