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))
