bug#62493: xelatex won't render fonts correctly without full texlive

[John Kehayias]

Hi Ricardo,

Note that I didn't get your replies as it was sent just to the debbugs
email (I always find it strange that the bug email alias doesn't send to
the submitter by default). This message from Simon was helpful for me,
at least via Emacs: https://issues.guix.gnu.org/59855#2 (perhaps you
already know or have some other method, but thought I'd mention it and
I'm open to more such tricks!)

Ah, that's good to know, thanks for figuring that out.

I also don't see any record of such a package. Trying

I'm not up to with texlive packaging, any tips? Or perhaps someone we
can ask for input here?

Thanks!
