I also have written a smaller function to display a quick information of a single character at point, something much simpler and not as verbose as describe-char. But it had never occurred to me to do something eldoc-like with it. In my case, although for those contexts I prefer quick information (describe-char also has its relaxing moment), I don't feel such an urgency :-). In any case, something quick and dirty, just as a proof of concept, could be this: (define-minor-mode char-info-at-point-mode "TODO" :init-value nil :lighter ("chinfo") (if char-info-at-point-mode (add-hook 'post-command-hook #'char-name-at-point nil t) (remove-hook 'post-command-hook #'char-name-at-point 'local))) (defun char-name-at-point () (interactive) (let* ((char-name (get-char-code-property (char-after (point)) 'name)) (code (format "#%x" (char-after (point)))) (dec (get-char-code-property (char-after (point)) 'decomposition)) (info (concat char-name " / " code " / descomp: " dec "\s" (mapconcat (lambda (cod) (format "#%x" cod)) dec "\s+\s")))) (message info))) Best regards, Juan Manuel
