I'm still skeptical about this kind of matching. I'd rather each application 
wrote the function that is specific for their needs.

In the specific case of Parley, "getting the accents wrong" isn't enough. You 
have to match other language specificities: for instance, in German, ö is the 
same as "oe" and ß is the same as "ss" (but not in all cases, AFAIU), but ß 
isn't the same as β (Greek Beta). The function you wrote will not catch any 
of those cases, so you still need to do some decomposition on your own.

Also, did you know that the function you wrote will strip the Hebrew vowel 
accents? In the case of Parley, I think this might be relevant.

By providing this function in KStringHandler, you open up room for lazy 
coding: the developer didn't really think through the issue.

PS: in any case, suggestions:
  add a noAccents.reserve(original.length());
  also match QChar::Mark_SpacingCombining and QChar::Mark_Enclosing
   (some Bengali vowel signs are non-spacing others are spacing)

PPS: NFKD normalisation turns ß into ss, DZ into D and Z, etc.
