;;; Commentary:
;; Loading this package defines three ways of entering the non-ASCII
;; printable characters with codes above 127: the prefix C-x 8, or the
;; Alt key, or a dead accent key. For example, you can enter uppercase
;; A-umlaut as `C-x 8 " A' or `Alt-" A' (if you have an Alt key) or
;; `umlaut A' (if you have an umlaut/diaeresis key).
;;; Code:
(defvar iso-transl-dead-key-alist
'((?\' . mute-acute)
(?\` . mute-grave)
(?\" . mute-diaeresis)
(?^ . mute-asciicircum) ;; Don't use \, since \^ is special.
(?\~ . mute-asciitilde))
