Hi TeX Guixers,

Ran into a curious problem today of xelatex not properly rendering what I think is a mapping/ligature issue: the usual TeX ``something'' quote syntax should become proper double quotes (for English at least) but don't.

Here is a simple test tex file:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
``test quote''
\end{document}
--8<---------------cut here---------------end--------------->8---

If you compile it with

--8<---------------cut here---------------start------------->8---
guix shell texlive-base texlive-fontspec -- xelatex test.tex
--8<---------------cut here---------------end--------------->8---

you'll see the same quotes as in the tex file. Full log (test-bad.log) attached but the relevant line looks to me like

--8<---------------cut here---------------start------------->8---
Document Class: article 2020/04/10 v1.4m Standard LaTeX document class
(/gnu/store/npkjqvkgzj3pfhqwbcc504kgp1z6fj8s-profile/share/texmf-dist/tex/latex/base/size10.clo
File: size10.clo 2020/04/10 v1.4m Standard LaTeX file (size option)
Font mapping `tex-text.tec' for font `[lmroman10-regular]:mapping=tex-text;' not found.
)
--8<---------------cut here---------------end--------------->8---

I did try adding various packages, changing fonts and font settings, but to no avail.

Meanwhile, using

--8<---------------cut here---------------start------------->8---
guix shell texlive -- xelatex test.tex
--8<---------------cut here---------------end--------------->8---

gives a nicely rendered double quote mark. The log (also attached as test.log) shows no such similar message.

Some searching the most succinct and relevant summary I think is here <https://tex.stackexchange.com/questions/193412/what-is-happening-to-the-quotes>

Anyway, seems like something is missing when we use the minimal packages, but I can't seem to find what to add to guix shell to change the output of the pdf. Probably it is not captured in a package or is otherwise lost?

Any ideas?

Thanks!
John

PS: I don't think it is related, but xelatex will complain about not finding a fontspec.cfg either. I made one locally from what it used to be, but didn't change the output for me. I think it went missing here:

I see you pushed some fixes for this (I didn't try with -r as that kept running for a while and might have tried to generate a whole lot of the dependency tree), thanks! I do get an import for xetex now.

And on that note I see cbf731ae481b434e657b05c80b4a32282e5d112b which adds texlive-xetex.

I can confirm with guix shell texlive-base texlive-fontspec texlive-xetex -- xelatex test.tex the output pdf has proper quotation marks and the log looks clean.

Many thanks!
John
