in thread Function over all letters in a string

Here's a little trick you can use in Latin1 character encoding (instead of locales) to avoid having to name all non-US word characters explicitly: just define the character set as [A-Za-zĄ-’]. If you look at a Latin1 character table, you'll see what it does--and it works for more than just German. :)

    Good point. But I think even more dangerous that using only [a-z] (my example, too). I think this should work quite well: 
          next CHAR if $c =~ /^[[:punct:][:cntrl:][:blank:]]$/;

    Add [:digit:] to exclude numbers, too.
