;; This is not really a Quail method, but uses some Quail functions.
;; There is probably A Better Way.
-;; Compare `ucs-insert', which explicitly inserts a unicoded character
-;; rather than supplying an input method.
+;; You can get a similar effect by using C-q with
+;; `read-quoted-char-radix' set to 16.
+
+;; Note that this only allows you to enter BMP values unless someone
+;; extends it to use variable numbers of digits.
;;; Code:
(require 'quail)
