I'm facing with UTF-8 encoding problem while persisting my model objects. In Turkish '**ı**' is a letter. Also there're some other Turkish characters that is included in UTF-8 encoding. While I persist my model objects, all '**ı**' characters are persisted as '**?**' to DB. I'm using **MySQL 5.5 on Ubuntu Linux 64-bit OS**. Also I've already set hibernate & c3p0 connection encoding property to UTF-8 too. When I debug, the data comes from client is true. 

Here's my config and I'll be so happy if someone can help me. 

Thanks in advance.
