What do you mean by "collation N" in all the columns? Do you mean we can't set 
the collation type from QCollation::Collation? If so, that's quite acceptable, 
the class should default to whatever the collation type is for the locale.

identifier: it would probably return "System" and that would be fine.

casePreference: looks like we can do case sensitive and insensitive, then. 
Sounds like an acceptable compromise. For POSIX, we can implement case-
insensitive collation by lowercasing, even though that might introduce some 

numericMode: this is what KDE wants. We can write our own algorithm.

sortKey: the lack of OS X support is worrying... didn't they have just a 
simple wrapper around ICU?

indexCharacters: we can return the English ones and see what happens...
