I'm pretty sure that Nicolai will explain things better; so it's better to
wait for his e-mail.
If PostgreSQL had a full unicode implementation, as you've said: Yes, we
would experience the same problems.
We also have a problem while sorting result in a SELECT query, which seems
a similar issue as this one. In Turkish, i-dotless comes just before i in
alphabet; but PostgreSQL places i-dotless 'after' i, which is a false
result. Nicolai will also report this bug, and explain why/how it happens.

This is what we've also thought in here.
