# PerlIO::encoding - phpMan

## 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().
