When I sign the guestbook using the greek language, the encoding is by default switched to WESTERN EUROPEAN (ISO). When I click on "Submit", I get this: One of the input fields does not seem to be valid.
When I manually change the encoding to GREEK (WINDOWS), it submits the entry. How do I make the encoding to be always greek by default? (I need greek encoding to all of the guestbook pages). Thanks for your time!
