Then thanks for resending, since I am not on any of the lists.
Adding `ccl-program-definition' did not directly fix the broken
conversion. It was practically necessary to figure what C code to
look at, and will remain so until no CCL coding system is ever used.
Will post separate patches on request.

Your change crashes a debug build of 21.5 when the following code is
executed:
(let ((ccl-vector [0 0 0 0 0 0 0 0 0]))
(define-ccl-program ccl-write-two-control-1-chars
`(1
((r0 = 143)
(r1 = 0)

(format "%c%c" (make-char 'control-1 0)
(make-char 'control-1 31)))
nil
"CCL's write-multibyte-character breaks for control-1! "))
This works okay, however:

There is a separate but similar problem with mule-to-unicode that I’m still
looking into.
