Problems with diacritical signs

[Greg-Z]

Need help.
When I'm trying to create a page on IMFDB that contains diacritical signs in text, I get the following error:

---
Database error
Jump to: navigation, search
A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function "LinkCache::addLinkObj". Database returned error "1267: Illegal mix of collations (latin1_bin,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=' (192.168.130.4)".

I encountered this problem when creating a page about a Romanian movie with original title "Un comisar acuză", and I had to change this title to "Un comisar acuza". The same problem was with several names of actors and characters. Well, I created the page with simplified (and a little incorrect) title and names. But later I found out that another user created a page "Mikuláš Huba" - so the title with diacritical signs can exist. But I still cannot add such letters. Can this problem be solved?

Thanks in advance!
Greg.
