  Yup, NCLX in 2000-3-6 is broken. Look in the file new-clx/clx.f. 
You'll see that they didn't implement XLIB:KEYCODE->CHARACTER. Also,
KEYSYM->CHARACTER doesn't do anything. (Otherwise, you could do
keycode->keysym then keysym->character.) You'll need to complain to
the CLisp guys.

  I believe the manual is wrong. All of the translation functions are
defined using "->" but the manual says "-" for them. I've never seen
the original source for the CLX manual, so I don't know if this is a
TeX error, a mistyping, or what.
