Major problem: z-with-dot letter seems to be screwed in links.
Links from
http://local_copy_of_wikipedia/wiki.phtml?title=Wy%C5%BCsze_uczelnie_w_Pols…
to subpages are broken.
They work on Polish UseMod Wikipedia, so it must be problem with conversion script.
Maybe there are some mistakes in latin2 -> unt8 table ?
