Terr!

I have a little script, which should from textfile input grab out every non-alpha characters and pipe then all alphas line by line to another function. I tried with [[:alpha:]] and \w/\W, but both work with diacritics (aka umlaut-chars) in one context but not in other. So i made an simple example script to show my point:

#!/usr/bin/perl

use strict;
use utf8;
binmode STDIN, ":utf8";
binmode STDOUT, ":utf8";

my $str = "See on üks täppidega lause!"; # sample string, want to get 
+rid of spaces and exclamation mark, all other are alphas, and i reall
+y need them

# first printout ( how [[:alpha:]] works)
foreach my $mrk ( split(//, $str) ) {
        if ($mrk =~ /^[[:alpha:]]$/ ) {
                print "$mrk";
        }
}
print "\n\n";
# end of first printout


# second printout  ( how [[:alpha:]] doesn't works)
$str =~ s/[[:^alpha:]]//ig;
print "$str\n";
# end of second printout

exit(0);

__END__

First output:
Seeonükstäppidegalause

Second should be also same, but is:
Seeonkstppidegalause

Why replace does not know that diacritics are also alphas? Or is there something wrong in my code? I can see workaraound (to write my own replace, for example), but i'd like to get it work in standard way.

Perl is v5.8.8, in Kubuntu 8.04.

TIA,

Kõike hääd, WK
