So, here's a patch I would like a couple of people to try before i
commit it. It provides customization of checkbox formatting for html
output (unicode, ascii, checkbox input fields or custom). I couldn't
figure out how to add an association list customization with preset
options to a customization choice, so the custom option is a
partilally pre-filled sexp.
The default is still ascii, partially so that the checkbox tests don't
fail w/o being changed.
Let me know if this works for every of if it is too complex a solution
befor I apply it to master.

A new buffer keyword (which needs to be documented in org.texi),
a defcustom with a completely free sexp... Isn't it a bit too much for
mere checkboxes? Filters provide almost the same functionality:
(defun my-checkbox-filter (item backend info)
(when (org-export-derived-backend-p backend 'html)
(replace-regexp-in-string "\\`.*\\(<code>\\[\\(X\\| \\|-\\)\\]</code>\\).*$"
(lambda (rep)
(let ((check (match-string 2 rep)))
(cond ((equal check "X") "☑")
((equal check "-") "☐")
(t "☐"))))
item
nil nil 1)))
(add-to-list 'org-export-filter-item-functions 'my-checkbox-filter)
Anyway, here are a few comments.

This looks cheesy. `read'? Do you really want to parse arbitrary Sexps?

Personally I think the defcustom is enough, as this choice is likely
to be made for all Org documents.

Yes, but a defcustom would be easier.

Can we re-work Rick's patch/code and add this feature? Rick,
are you still on it?

As long as it doesn't let you write completely free sexps. Otherwise,
a function is equally complex.

I agree. But this is a very minor issue with Rick's patch,
the bulk of the work is done and I'd be glad to see it applied,
with the limitations we've been discussing. If Rick is on it,
let's wait for this.

Bastien-
Top quoting to keep the history but save the search to the bottom
:)...
Yes, i will rework/simplify the patch (remove the free-form option and
the in-buffer setting), but I've been short on time the last week or
so.. Will fix it and push this week.
BTW, I've kept ascii output as the default mostly so I don't break the
regression test. Should I leave it alone or make utf-8 the default and
update the test?

I'm for keeping the ascii output as the default one,
but if people prefer the utf-8 one, so be it.
