non-math superscripts in LaTeX export

non-math superscripts in LaTeX export

Hi,

This file:

Math mode: a\(^{b}\)
Non-math mode: a^{b}
What I'd like: a\textsuperscript{b}

Is exported to this LaTeX code:

Math mode: a\(^{b}\)
Non-math mode: a\(^{\text{b}}\)
What I'd like: a\textsuperscript{b}


When viewing a PDF from that LaTeX source, the first (Math mode) appears correct. The second (non-math) appears correct in the PDF, but I'm not sure it is in the LaTeX source. The third looks correct.


A more severe end-product appearance issue comes downstream. I find Pandoc generates better ODT and DOCX files than Org when the inputs are complicated. When viewing a DOCX generated from the above LaTeX with:

$ pandoc -f LaTeX -i foo.tex -t DOCX -o foo.docx foo.tex

there is a more serious issue: The b power is not attached to the a, so there is an empty box and it looks like this (where ^b is actually raised as a superscript):  a[]^b. Or see attached screenshot.

I've tried toggling #+OPTIONS ^:{} and ^:nil but it doesn't solve this. It seems to me like a^b should export as a\textsuperscript{b}. Do others agree? Or is this a pandoc bug I should be raising in that project?

Thanks,

  -k.

I know pandoc is not the Org reference implementation, but digging into this further I noticed that pandoc exports a^{b} from Org to LaTeX the way I expected/hoped Org would:

$ echo "a^{b}" | pandoc -f Org -t latex
a\textsuperscript{b}

  -k.

I think you're right. I changed "ox-latex" to use \textsubscript and
\textsuperscript in master. Could you check the result is correct now?

Thank you.

Seems to work.

I spent ~10 minutes browsing the code before I wrote the list, because I would have liked to submit a patch rather than just a comment/question. After your quick reply I thought "this must have been fairly easy" and I went and looked at the changeset

https://code.orgmode.org/bzg/org-mode/commit/0811af50b49de832b74222189695a09327ef6e6b

I would love to contribute more to this project but am still far from being able to do what you just did there.

Anyway... I'd have a hard time doing my work without Org, and I'm once again reminded that Org is People. Thank you for helping maintain and improve it!

  -k.
