Make sure:

* You have saved your script in UTF-8, not Latin1
* use utf8 to make sure string literals are treated as UTF-8 strings
* if you print, set filehandle layer to ":utf8".

Try the sript below (be sure to save it in UTF-8).  I got "KÄThe => 
käthe".

#
use strict;
use utf8;
my $fname = 'KÄThe';
my $lc_fname = lc($fname);
binmode STDOUT => ":utf8";
print "$fname => $lc_fname\n";
__END__

You should upgrade it to 5.8.1 or above (5.8.5 being the latest).  
5.8.0 was still premature unicode-wise.
