High-Order ASCII Alphabet & Other Keyboard Edits

Mark, et al:

My purpose is to filter individual keystrokes as a user is typing in 
an input field.  The filter intercepts keyDown messages and, if a 
field is defined as a positive integer in the Data Dictionary, 
terminates the message if the key pressed is not between "0" & "9". 
If the field is defined as an uppercase English alphabetic field, the 
filter terminates keyDown messages if the key is not between "A" & 
"Z".

My underling question is:

Suppose I want to define a field as an uppercase German alphabetic 
field.  Which high-order characters does the filter pass to the field 
and which ones should be rejected?
