Hi you all,
thanks for all the input, I agree that this would only be a temporary 
solution. So it should definitively not go into KStringHandler.

Can you point me to further material on stringprep? I looked briefly but could 
not find anything really helpful.

Right now I just want to be able to give feedback of the kind "you have made 
an accent mistake", instead of just saying "you are wrong".
KHangMan and Kanagram will use it to check if the right letter was entered 
because for the HangMan game for example using all accents and everything can 
be a little too complicated (target audience are children).
These are all rather limited cases and I hope we won't run into trouble with 
other languages.
As we all know computer linguistics is not an easy field, so I would be happy 
about further suggestions. I also started looking at some spellchecker code.

I agree with Torsten insofar as that after reading the Qt docs I didn't 
realize the unicode decomposition was what I wanted. Maybe some hint could be 
added to the documentation. I realized this should be possible with Qt only 
after reading a lot of the unicode.org stuff (not fun) and then some of the 
ICU docs. Afterwards the Qt docs made more sense, but still tough.

So for now we'll leave it in the individual apps.
Thanks again,
Frederik
