Gnue and Greek UTF-8

Hello all.

Sorry from my bad English.
I have one problem with gnue and greek utf-8.

Storing all data in Mysql and my database support utf-8.
If write data(greek) in field on gnue-form view and storing normally.
But if try to read the data from my database (F8), the gnue-form do it 
search and the come back chars is incomprehensible.

best regards...
