One has to draw the line at something. Although I am just a user I feel
this falls into the same category as the request from last year to make
the stars in a headline configurable. This is an integral part of org
syntax.
Last time during the customisable headline thread this was discussed
extensively and the core developers agreed that making org syntax
customisable defeats interoperability and breaks external tools written
to parse org files.
That said, I believe you can customise how these check boxes are
exported to various backends. AFAIR, there is a nice thread discussing
the case for latex export from the end of last year.
Hope this helps.
Cheers,

Granted. :-)

Well, Org mode is built over Outline mode, stars are coming from there.
While [?] are pure Org mode additions, so Org "owns" it better...

Exactly my objection to my own suggestion.

Oh, I was not at all thinking about export. Just my own pleasure while
editing Org mode files within Emacs. :-) Not a big deal, of course.

True, in the discussion about stars I believe the suggestion was to use
a regex for the headline marker in outline-mode. But the majority
opinion was it would be too fragile. Your argument that org owns this
better is probably correct, but I am no expert. Nicolas is the list
expert, he will be able to say how easy/feasible/difficult it would be
to make this customisable.

Allowing to configure TODO keywords is mandatory if we aim at providing
a decent tool for project planning. On the other hand, customizable
check-boxes is only icing on the cake and doesn't add any
functionality. Hence, I wouldn't call it a "kind of precedent".
I don't think that we should allow basic structural elements to
change. As you said, it will make Org documents less interoperable, but
also less _recognizable_. What would happen to Org if every user could
come up with its own syntax? Could we even talk about an "Org format"
anymore?
I'd rather keep it simple and consistent. It may be a bit ugly at times,
but don't we all feel at home with plain text?

We surely do. Yet, now that we all swim within Unicode -- aren't we?

:-). Come on! UTF-8 has been *designed* so all Americans could rightly
claim, out of the box, that they comply and are using it when they
write, without having to change the slightest iota in their work habits.
Reading UTF-8? No problem either, given it has been written by other
Americans. UTF-8 from other countries? Oh! That's another story... :-)

M. Pinard may want to look into changing the way that glyph displays...
If we were to define a font face which was used for checkboxes, he
could then specify for that font an edited font which displays his
desired checkmark in the character formerly knows as 'X'.

You probably could use display strings so the file on disk won't
change at all.

How about a variation of this
#+begin_src emacs-lisp
(font-lock-add-keywords
'org-mode `(("\\[X\\]"
(0 (progn (compose-region (match-beginning 0) (match-end 0)
"✓")
nil)))))
#+end_src

Btw, C-h f org-toggle-pretty-entities does composition and decomposition.

I like the idea... Here is another alternative:
(font-lock-add-keywords
'org-mode `(("\\[X\\]"
(0 (progn (compose-region (match-beginning 0) (match-end 0)
"☑")
nil)))
("\\[ \\]"
(0 (progn (compose-region (match-beginning 0) (match-end 0)
"☐")
nil)))))

New concepts for me in this `compose-region'! Handa-san strikes again! :-)
I confess I do not understand much of it. Ctrl-S being turned into a
rectangle is mysterious. Is it the standard way for Emacs to tell about
a non-printable character? The documentation of font-lock-add-keywords
does not hint me at what may be those S-exprs which are not faces.
Moreover, the effect is a bit tiny or shy, at least compared to what I
expected. The suggestions of John Miller yield tiny characters as well.
Presumably, I could try to see if I can force higher font sizes, but
that would be diving deeper into trickery, and away from other problems.
Despite the undoubtedly ingenious suggestion, I guess I'll merely stick
with what Org mode already offers, as it's the best I got so far! :-)
In any case, I'm grateful for your interest, and for sharing ideas.

There is no Ctrl-S character only a tick mark in the compose-region
snippet that I shared.
You can see the tick mark if you follow this link:
http://article.gmane.org/gmane.emacs.orgmode/52281
The tickmark is produced by
M-x ucs-insert RET CHECK MARK RET
If the above command doesn't yield a tick mark the issue is with your
setup. May be copy-paste from your Emacs client to your Elisp file
garbled the characters?

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?
> If the above command doesn't yield a tick mark the issue is with your

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! :-)
