;; The iso-accents-compose function is called deep inside Emacs' read
;; key sequence machinery, so the call to read-event below actually
;; recurses into that machinery. Doing that does not cause any

;; display matrix to be accurate -- which is broken by the subsequent
;; call to delete-region. Therefore, we must call force-window-update
;; after delete-region to explicitly clear the accurate state of the
;; window's display matrix.
