See utf8 filenames I ran into a similar problem awhile ago, and graff gave me this sub to fix the problem

#this decode utf8 routine is used so filenames with extended
# ascii characters (unicode) in filenames, will work properly
use Encode;
opendir my $dh, $path or warn "Error: $!";
my @files = grep !/^\.\.?$/, readdir $dh;
closedir $dh;
# @files = map{ "$path/".$_ } sort @files;
#$_ = decode( 'utf8', $_ ) for ( @files );
@files = map { decode( 'utf8', "$path/".$_  ) } sort @files;
