VirtueMart Search Product and special characters

[deni]

Hello,

I'm not sure if I'm posting this in right place, but here it goes.

I have Joomla! 3.3.6 Stable and VirtueMart 3.0.2 and one big problem, VirtueMart Search products results with Error 404 page when searching articles with special characters "č", "ć" and "đ", but it works fine with "š" and "ž". When I use "c" instead of "č" or "ć" and when I use "d" instead of "đ" search results are fine (the articles with "č", "ć" and "đ" are found then as well), as they are with š and ž.

Encoding is UTF-8.. And one more thing, Joomla's Traction Template main site search works fine like charm, even with searching products from Virtuemart shop with "č", "ć" and "š"..

Could someone please help me resolving this? I lost 9 days for that and deadline is near so I don't have much time for solving it..

P.S. Site and shop are on Croatian language.

Thank You in advance and best regards,
deni

EDIT: You can see what happenes on link: http://www.mojskuter.com/index.php/webshop/webshop, just type "cok" to "BRZA PRETRAGA" - "Traži" and after that type "čok".
