Friendly URLs for UTF-8 characters (č,ć,?,?...)

[webmajstorinet]

Greetings everyone,

is there a character replacement for URLs available in core vBulletin? I know that the VBSEO can do it.

Here is one example
http://www.webmajstori.net/forum/tema/37432-%C4%8Clanak-Anonymousi-Na%C5%A1-virus-%C4%87e-16-travnja-uni%C5%A1titi-internet%21

That i would prefer to be like this
http://www.webmajstori.net/forum/tema/37432-Clanak-Anonymousi-Nas-virus-ce-16-travnja-unistiti-internet

I've selected "Convert to UTF-8" under the "Friendly URLs" option.

I am afraid that this kind of link structure might hurt the SEO rankings. Any ideas?

Thank you
