[SOLVED] Language change in header of Template18

Hallo, I would like to change the language of the titles in the header to greek. Even though custom.xml is in UTF-8 which normally is good for greek, it seems to have a problem. Greek doesn't appear on the header , only latin characters can. I changed it to greek ISO , but the problem remains.
Could you please help me?
