Bénin in incorrect place	Côte d'Ivoire in incorrect place

We need to take into account diacritics also - right now if a letter has a diacritic it is put after all letters without diacritics. So in the above examples (using French) Bénin should go after Belize, and Côte d'Ivoire should go after Costa Rica, etc.

I think this is a valid concern, but should be filed as a separate task, as it most likely also affects topics etc.
