You could implement the same check as read-char:

(defun character-event-p (event)
   "Return non-nil if EVENT is a character event."
   ;; see Fread_char:
   (if (symbolp event)
       (let* ((mask (get event 'event-symbol-element-mask))
              (char (if mask
                        (get (car mask) 'ascii-character))))
         (if char
             (setq event (logior char (car (cdr mask)))))))
   (integerp event))
