I found this by trying to export Bernt Hansen's org-mode tutorial
[1] to
HTML and LaTeX. Bernt's IRC nick is Thumper_ and it appears in the
AUTHOR option as follows:
#+AUTHOR: Bernt Hansen (IRC:Thumper_ on freenode)
When exported to HTML, everything is fine. When exported to LaTeX,
LaTeX
complains about missing $. The problem does *not* arise if the
underscore
is in most other places in the org file, but I found one more place
where it
does arise: in a headline, when the underscore begins the word.
Here is a small test file (hi, Sébastien;-) :
--8<---------------cut here---------------start------------->8---
#+AUTHOR: Nick (nick_)
#+OPTIONS: ^:{}
* foo foo_bar foo_ _bar
foo
foo_bar
foo_
_bar
--8<---------------cut here---------------end--------------->8---
Everything works except the nick_ on the AUTHOR line and the _bar in
the headline.
