Question Enter greek characters in MySql DB?

[gate7cy]

I am trying to insert greek characters to my database and I keep getting and '?' question marks inserted. I am using VS 2008/MySQL server 5.0. I have googled it and everyone who had the same problem before were developing webpages and not software. The changes they did to resolve had to do with php code and something with setting up character set. I change my collation in MySQL but VS works with datasets. Do I have to do any changes in the setup of VS? If yes, which? Thanks for your efforts guys. great site!!
