latin1 to utf-8 I really tired :(

[schmidt123a]

Hello.

I working 3 days on this issue to convert latin1 to utf8

Things which I done:
- Converted database to UTF-8,tables,collations,and text inside database looks correct,I mean symbols are correct like I wanted.

But now I have one last biggest problem:

All this nice symbols which looks correct inside database on vbulletin they looks like this:

Man pavyko ?rodyti, kad esu vienas i� penki?

charset is correct:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

Inside config.php I was trying to use mysqli option with:

$config['Mysqli']['charset'] = 'utf8';

But this never helped when I use this option all my style crashed and language text gone.

Also I think that php is connectin with latin1 charset to database but where I need to change it to utf8 ?

So where is the problem please help ?
