Thanks!
I did activate that checkbox Beta: Use Unicode UTF-8 for worldwide language support while experimenting last week, but since then I have switched back and rebooted several times. Now it is definitively deactivated. Could this be a caching effect?

Also I wonder, how would you write the test for Win32::getACP() to actually compare the return value against the value reported by windows. Currently it is like this and rather coarse: 

use strict;
use Test;
use Win32;

#plan tests => 8;

my $ansicp = Win32::GetACP();
ok($ansicp > 0 && $ansicp <= 65001);
