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().
