This was the only example that I was able to come up with (but the
library wasn't installed by default which is probably a problem; and
the module doesn't provide Serbian collate rules for example):

use encoding 'utf8';
use Unicode::Collate::Locale;

$Collator = Unicode::Collate::Locale->new(locale => "sl");
my @sorttest = qw(cd ab ča št de tu si);

@sorted = $Collator->sort(@sorttest);
foreach my $a ( @sorted ) {
    print "$a\n";

The following without any exotic libraries didn't work:

use encoding 'utf8';
use locale;
use POSIX qw(locale_h);

use warnings;
use strict;

setlocale(LC_CTYPE, "sl_SI.UTF-8");
my @sorttest = qw(cd ab ča št de tu si);
@sorttest = sort(@sorttest);

foreach my $a ( @sorttest ) {
    print "$a\n";

print "\n";

print +(sort grep /\w/, map { chr } 0..255), "\n";
