wrong encoding. Greeks don't show write = ..........???? is what i see

hello to everybody. this is my first post and unfortunately is about trouble.

i install the demo site, and start change things, but when i write Greeks i don’t get any characters. Only ...?.........?????

i was suspect ii was encoding trouble, but i check the System configuration Greek Iso, and everything was fine.

Any idea?
