NAME

PerlIO::encoding - encoding layer

SYNOPSIS

  1. open($f, "<:encoding(foo)", "infoo");

  3. use Encode qw(:fallbacks);
  4. $PerlIO::encoding::fallback = FB_PERLQQ;

DESCRIPTION

Open a filehandle with a transparent encoding filter.

On input, convert 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, convert 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 Encodings encode and decode.
