There is a SYS()-function for character translation. You can convert any unwanted characters to nothing, or to a special character and then check for this character or remove it with STRTRANC.

Or you could convert any good characters to nothing or a special character and then check if there are any unwanted characters left.

Also, you can use the inputmask-property of a textbox to avoid that unwanted characters are typed in the field.
