--- Comment #3 from Ketmar Dark <ketmar at ketmar.no-ip.org> ---
while you are completely right here, OP didn't asked for correct unicode-aware
permutations (and dchars cannot support that too, by the way), he is just
telling that premutation of *chars* isn't working. so my `.byChar` solution
does actually solving OP's problem, and it does that perfectly. ;-)
