When converting from Typst, primes are handled incorrectly

[John-Toohey]

Consider the following Typst file:

$ f'(x) = x^2 $

Which renders as:

When run through pandoc pandoc a.typ -o a.md the following output is generated:

$$f\prime(x) = x^{2}$$

Which, when converted to PDF via pdflatex, looks like this --- with an incredibly chunky prime sign:

This is incorrect. Rather the markdown should be (notice the superscript):

$$f^{\prime}(x) = x^{2}$$

Pandoc version?
pandoc 3.1.11.1 running on NixOS unstable. Also tested on https://pandoc.org/try/

As I understand it, this expectation is not correct. You should not need to manually superscript the \prime in LaTeX. This is a function of the font not fully supporting the expected layout features.

Another iteration of this problem can be seen with layout engines (including Typst) that try to over-compensate and move something that the font has already made into a superscript manually smaller and in a higher position resulting in a doubly small and high superscirpt. I believe this has been at least partially addressed in the latest Typst devel version, but the last stable release still shows this problem, e.g. with Libertinus Math. You can see the effect here:
