Well, I suspect most of this charset handling is obsolete. so setQFont etc 
will become effectively a null function encapsulated in #ifndef 
KDE_NO_COMPAT.

I'll have a look which part of the API might be useful for other things, the 
rest will be dropped. Suggestions welcome.

Yes, another part is QTableView and QMultiLineEdit, which we use in several 
places in kdelibs.

good idea.

Yeah, but both should make the life much easier.

I think Simon did most of the necessary API changes there already. I'll have 
a look at the rest.

I personally don't thin its worth the effort keeping track of this.
