    Major Section:  ACL2-BUILT-INS

Completion Axiom (`completion-of-code-char`):

    (equal (code-char x)
           (if (and (integerp x)
                    (>= x 0)
                    (< x 256))
               (code-char x)
             (code-char 0)))

Guard for `(code-char x)`:

    (and (integerp x)
         (>= x 0)
         (< x 256))

ACL2 supports 8-bit characters. Inputs not between `0` and `255` are treated as `0`.
