Oops, indeed!

Checking more closely on the message you originally sent to me (with a
Cc: to the mailing list)...  There were two check marks in the message.
If I open the message raw in Gnus (`C-u g' in the summary buffer), I see
both of them coded as =E2=9C=93.  But if I let Gnus to render the
message, while the first check mark is OK, the second gets mangled into
a Ctrl-S.  Could it be a problem with the Gnus rendering mechanics for
whatever sits between #+begin_src and #+end_src?

Changing the Ctrl-S by the check mark, within ~/.emacs, now makes much
more sense!  I'm getting exactly what I wanted through this writing,
inspired from yours (thanks, Jambunathan!):


(font-lock-add-keywords
 'org-mode
 '(("\\[\\(X\\)\\]"
    (0 (progn (compose-region (match-beginning 1) (match-end 1) "✔") nil)))
   ))


I'm being lucky here, as I only barely understand what the incantation
means! :-)
