GOautodial Open Source Omni-channel Contact Center Suite

I'm trying to load some leads with greek letters in it and i'm getting the follow in my agent screen:

I'm uploading the leads in UTF-8 format and after changing the latin1_swedish_ci of the fields in the vicidial_list to utf8_general_ci managed to view in the database tables my leads correctly. Still when i try to view it from my agent front end i'm getting the same ????? i got before. Is there any other field that needs to change collation in order to be viewed properly? I use the goautodial 3.3 pack and even by enabling the mbstring.dll and configuring it to use UTF-8 i still get ??? from the database (i rebooted apache to read the php.ini again). If i manually add greek letters from the agent frontpage it's insterted correctly and show properly but in the database i'm getting this format "τεστ" for the word "????". From what i can see agent.php has "charset=utf-8" in his meta.
