Indeed that is the case. We may not rely on Qt's tables because we don't know 
what is contained in them. And we need the "additional folding" rules and a 
couple of others that aren't there anyways.

We've more or less settled down for using the implementation in libidn or 
maybe a similar library (it seems there is one from JPNIC and one from 
Verisign). At the moment, we're developing KDE with libidn and I found in 
your library the very functions I wanted.

The resolver part of the code is more or less settled. I wonder how support 
goes in the URL part now...
