NAME

6       PerlIO::encoding - encoding layer
7

SYNOPSIS

9         use PerlIO::encoding;
10
11         open($f, "<:encoding(foo)", "infoo");
12         open($f, ">:encoding(bar)", "outbar");
13
14         use Encode qw(:fallbacks);
15         $PerlIO::encoding::fallback = FB_PERLQQ;
16

DESCRIPTION

18       This PerlIO layer opens a filehandle with a transparent encoding
19       filter.
20
21       On input, it converts the bytes expected to be in the specified
22       character set and encoding to Perl string data (Unicode and Perl's
23       internal Unicode encoding, UTF-8).  On output, it converts Perl string
24       data into the specified character set and encoding.
25
26       When the layer is pushed, the current value of
27       $PerlIO::encoding::fallback is saved and used as the CHECK argument
28       when calling the Encode methods encode() and decode().
