Hi,
sorry for bothering you again with it, but I'm having a problem with latex
inside footnotes and I couldn't find the answer in the manual.
When I try something like:
----8<---
blablabla [fn:bla]
[fn:bla] this is what \cite{she} said.
----8<---
this gets exported as:
---8<---
blablabla \footnote{ this is what \cite\{she\} said.
---8<---
I believe I'm missing something very basic.
I believe that if I put a "#+Latex:xxx" the xxx part would be exported
verbatim to the latex file. But this would break the footnote. Is there a
way to insert inline latex snippets?

Also, I have problems with equations even when I use \(...\) instead of
$...$.
This, for example:
--8<--
* example
Example[fn:note].
[fn:note]An equation: \(\bar{a}\).
---8<--
becomes this:
---8<---
Example\footnote{An equation: \(\bar\{a\}\). }.
---8<---
I'm not really sure, but I suspect this worked before I instaled the latest
version of org-mode.
Sorry for any inconvenience.

Unfortunately, the LaTeX exporter does have a lot of weaknesses in this
area: it tends to escape special characters willy-nilly - sometimes
that's the right thing to do, sometimes not.
This particular escaping is done by org-export-latex-special-chars: this
basically loops over four (horrendous-looking) regexps and tries to find
all matches in the buffer for that regexp. It then proceeds to transform
the matched text (and matched pieces of text *around* the main match) in
some (hopefully meaningful) way. In this case, it fails.
The only way I know around this problem is a mechanism that Tom Dye
describes in his (excellent) LaTeX exporting tutorial on Worg. He
credits Lawrence Mitchell for the case that he describes in the tutorial.
Evaluate this expression
--8<---------------cut here---------------start------------->8---
(setq org-entities-user '(("l" "{" nil "" "" "" "")
("r" "}" nil "" "" "" "")))
--8<---------------cut here---------------end--------------->8---
and then export the following:
--8<---------------cut here---------------start------------->8---
* example
Example[fn:note].
[fn:note] An equation: \(\bar \l a\r \).
blablabla [fn:bla]
[fn:bla] this is what \cite\l she\r said.
--8<---------------cut here---------------end--------------->8---
The trick fools the exporter but there are added spaces - I know no
way to get rid of those.

I doubt that. Although patches have been applied to deal with a host of
such problems, it is a long-standing problem that is unlikely to be
completely solved - ever[fn:1].

Footnotes:
[fn:1] ... although I would love to be proved wrong.

Yes, we need to rework the way the exporters handle espace chars,
especially the LaTeX one --- it's not only ugly and buggy.
Don't hold your breath though, I won't be on this before 7.7.
Thanks for your understanding,

Hi Bastien,
I have enough interest in using org-mode to produce latex texts to get
involved. I can't do it right now cause I'm in a critical time to produce
results for my thesis, but I've been delaying learning e-lisp and taking a
good look on org-mode for some time.
Nick Dokos above said that org-mode uses a huge regexp to parse the latex.
When this pressing phase pass I'll certainly take a look on that. I played a
bit (only a bit) with funcional parsers in Haskell (monadic parsers and
parsers based on arrows) and, in my experience, they are much, much more
easy to write and more powerful than regexp's (they can parse html! :D).
Well, lisp is functional... Maybe I'll take a look at this in the near
future.

I have pushed a fix for that problem in master. May you try it to
confirm it works (or not...)?
