 PerlIO::encoding - encoding layer

SSYYNNOOPPSSIISS #

   use PerlIO::encoding;

   open($f, "<:encoding(foo)", "infoo");
   open($f, ">:encoding(bar)", "outbar");

 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 eennccooddee(()) and ddeeccooddee(()).
