Aloha Richard and Carsten,
Thanks very much for this improvement. Math appears to work as
expected in the title and in figure captions. I haven't noticed any
adverse effects yet, but I've spent most of my time admiring the
well typeset titles :)
Hi Thomas,
thank you for being such a reliable member here.
Cheers
- Carsten
All the best,
Tom

Hi Richard,
I have now applied this patch. I am not entirely sure it will
have no adverse effects, so please, people who do export to LaTeX,
check after the next pull if you see any problems.
Actually, I think I have just found a better way to solve this issue,
in a way that will also solve it for figure captions.
Please, LaTeX export users, test the current git version.
THanks
- Carsten
Thanks Richard!

Hi all,
This patch fixes the issue I originally described here:
http://article.gmane.org/gmane.emacs.orgmode/32281
It preserves math-mode delimiters (e.g. "$" and "\(") in the
document
title when exporting to LaTeX. (That is, it prevents them from
being
escaped, by running the title through org-export-preprocess-string,
which marks them with the org-protected property.) It should work
regardless of whether the title is pulled from a headline, from
the text
before the first headline, or from an explicit #+TITLE declaration.
(This is my first time contributing a patch to a Free Software
project
-- so please, let me know what you think!)
Best,
Richard
