if you're going to do case-insensitive comparisons then you need a
case-insensitive collation. UPPER is a workaround. For
accent-insensitivity, you need an accent-insensitive collation. In the
case of accents, there's not even a workaround.

Now, the problem is that AFAIK Fb2 doesn't include any CI or AI
collations for western languages out of the box. :-(
