I ran into trouble when trying to match my scandinavian characters åäö using \w in a regexp. I wrote a shorter test script like this:

use warnings;
use strict;
use locale;

if ("ö" =~ /\w/) {
    print "^_^\n";
} else {
    print "T_T;\n";
}

On second thought this could maybe be more of a linux question though, I tried running the script encoded as latin-1 on both my ubuntu and windows PC and it ran fine on windows but not linux. So where would I go to resolve it?
