	To which I'd suggest the programmer (vs the user), probably needs to
code some sort of per-character validation check... After all, there may
be situations where accepting pretty much any key-code is desired, and
if the widget filters characters before they get to the programmer level
that becomes impossible.

	caveat -- I've only written one simple form using Tkinter, so what
do I know...
