CL: Check which CODE-CHARs do not yield characters
(defun char-check ()
"Print all codes for which (code-char a) returns nil and return their number.
If this returns nonzero, there is a hole in the code-chars,
so be careful.
If this returns 0, the implementation is effectively
NIL-proof in this case.
NIL-bearing so far:
CCL 1.11-r16635 on Win32, beginning at 55295. 2048 codes (D800-DFFF) under 1114112 have a (code-char code) -> nil.
NIL-proof so far:
