No, I=CA=BCd forgotten about one of the corner cases of
`key-description'. `key-parse' would work here, but that probably has
other issues, so specifying the vector is your best bet.

Hi Robert
I just tried using key-description, for example
(define-minor-mode math-typing-mode
"A minor mode for typing maths characters"
:init-value nil
:lighter " Math"
(let ((map (make-sparse-keymap)))
(if math-typing-mode
(progn
(define-key map (kbd "C-3") (key-description "\u00B3"))
(use-local-map map))
(use-local-map nil))))
but this produces the same result as
(define-key map (kbd "C-3") "\u00B3")
while
(define-key map (kbd "C-3") [?\u00B3]) or my original lambda works (inserts
the unicode character when you press C-3)
Probably I misunderstand what you are suggesting though?

(info "(emacs) Init Rebinding") describes how to do this. The

--text follows this line--
Attempting to bind unicode characters (e.g. \u111E) to keys in a minor mode
with syntax like
(define-key my-test-mode-map (kbd "c") "\u221E")
usually works. In this case, C-h k c shows
c runs the command #<string CB7> (found in my-test-mode-map), which is
a keyboard macro.
It is bound to c.
Macro: M-\20636
Keyboard macro.
However the same syntax fails for some characters (so far I've noticed this
for \u00B0 to \u00B6 but there will be more) e.g
after (define-key my-test-mode-map (kbd "a") "\u00B2") C-h k shows
a runs the command #<string B6B> (found in my-test-mode-map), which is
a keyboard macro.
It is bound to a.
Macro: M-2
Keyboard macro.
and the effect of pressing "a" is to invoke command-digit-argument rather
than insert the required character
A workaround is to use a lambda expression to bypass whatever emacs is
doing when processing the unicode character, e.g.
(define-key my-test-mode-map (kbd "b") (lambda () (interactive) (insert
"\u00B2")))
and then this does insert the character (superscript 2) when "b" is pressed=
.
To replicate:
1. run emacs -Q
2. paste the following into the scratch buffer:
;; This buffer is for text that is not saved, and for Lisp evaluation.
;; To create a file, visit it with =E2=80=98C-x C-f=E2=80=99 and enter text=
in its buffer.
(progn
;; 1. Explicitly create the keymap variable and initialize it.
(defvar my-test-mode-map (make-sparse-keymap)
"Keymap for `my-test-mode'.")
;; 2. Define the minor mode, telling it to use our explicitly created map=
.
(define-minor-mode my-test-mode
"A test minor mode."
:global t
:lighter " my-test"
:keymap my-test-mode-map
)
;; 3. Define keys on the explicitly created and linked map.
;; normal bind fails at least for characters in range \u00B0 to \u00B6, but
probably more, e.g. \u00B2
(define-key my-test-mode-map (kbd "a") "\u00B2")
;; workaround is to use a lambda
(define-key my-test-mode-map (kbd "b") (lambda () (interactive) (insert
"\u00B2")))
; normal bind does succeeds with other characters I've tried so far, e.g.
\u221E
(define-key my-test-mode-map (kbd "c") "\u221E")
;; 4. Enable the minor mode.
(my-test-mode 1)
)
=3D=3D=3D
This creates a new mode "my-test-mode" with the key maps and puts it into
effect. Then try pressing a, b and c.
