> Nitpick: Single bytes also work in the 128-255 range, so it is rather ISO-8859-1 than ASCII. For example, an (ä) encoded as chr 0xE4 matches qr/\w/, according to its unicode property.

I can't reproduce this, from what I see is \w defaulting to pure ASCII

C:\Users\rolflangsdorf>perl
$a=chr(0xE4); print "$a matched \\w" if $a =~/^\w/;
__END__

C:\Users\rolflangsdorf>perl -v
