Special Character (such as ?,?,?,?,ü)

Hi, i love the Caldera Forms but something made me upset. I made a contact form and it’s fine. There is a field for name of the message sender. I want this field to be filled in with only alphabetic character (I don’t want anyone to write some numbers as their name). So I used a mask.
It works fine but i realize i cannot use some special Turkish characters such as ?,?,?,ü,? in this field now. I don’t know what to do. If anyone will help me, i will be most gratefull. Thanks in advance.
