Visible/Printable characters

How do I make Java tell me whether a certain character is a printable character, such as digits, letters, punctuation signs, whitespace etc. (all characters that have some effect when added for instance to a text field), such do NOT include chars like backspace, delete, F(1-12), home, end etc.
Looking through the static methods of class Character I didn't find anything that would do that.
