Hi. I think there's a bug in org-mode, related with subscripts and superscripts. This is the problem: pastie.org/9142947 And here's the related documentation page: http://www.gnu.org/software/emacs/manual/html_node/org/Subscripts-and-superscripts.html "To avoid interpretation as raised or lowered text, you can quote ‘^’ and ‘_’ with a backslash: ‘\^’ and ‘\_’." I think that's not working (adding a backlash to avoid interpretation of raised or lowered text). I'm using 24.3.50.1 with Xubuntu.
