Internal Program Version: Encode::Locale  1.05.5.42.0

In many applications it's wise to let Perl use Unicode for 
the strings it processes. Most of the interfaces Perl has 
to the outside world are still byte based. Programs therefore 
need to decode byte strings that enter the program from the
outside and encode them again on the way out.
