When I export to PDF via org-mode (C-c C-e d), any words with underscores end up being partially converted to subscript. How can I prevent this from happening?
I found this article on the subject:
Disabling Underscore subscript in Emacs Tex Mode
However, I either wasn't able to figure out the correct elisp or it simply didn't work. Note, I don't want to change any global font options. I only want this fix to apply to tex/latex/org-mode.
I also found this post, though it didn't work either:
You can disable super/subscripting within an org file by adding the following line:
#+OPTIONS: ^:nil
Check the org manual for more options.
The following command inserts a template containing all the options:
C-c C-e #
I was able to solve the issue by setting the following variable:
(setq org-export-with-sub-superscripts nil)
I think this would be easier: http://orgmode.org/manual/Subscripts-and-superscripts.html Escape the underscore with a backslash:
Now, escape the _:
You can see this in action here: http://www.railsonmaui.com/blog/2013/04/27/octopress-setup-with-github-and-org-mode/
Do you want to prevent subscripts in the onscreen display of the source file or in the text of the output PDF? If the latter, then you want
\usepackage{underscore}
It won't break the use of underscores in maths mode, either.
For individual cases, insert a literal underscore this way:
text text one\textunderscore{}two text
In my case any word that contains an underscore is likely to be a variable name or something similar. I just surround it with = or ~ so that it's treated as such. Then it will be exported accordingly.
