Hello Timothy, I love what you and Karthink have done here! Typesetting is
so much faster now! And the little nuggets like error reporting and
intelligent sizing & coloring is so going to boost my org QoL. Thank you
so much for your work!
I've been trying this on and off for a few days now, and it works really
well, except for one thing. I'm using XeLaTeX, and whenever I typeset a
LaTeX fragment containing a letter that sticks below the baseline (g, j, y,
etc), the fragment is typeset too small, almost like subscripts. It
reproduces when this is the only setting I have:
(use-package org
:ensure nil
:custom
(org-latex-compiler "xelatex") ;; drop this line and the issue goes away
)
Minimal 1-line org file to trigger the bug:
abc $d$ $y$ -- the y is typeset too small compared to abc. The d is just
the right size.
You mention in a separate email that XeLaTeX is known to cause hassles, but
is this one of them? I could migrate to PDFLaTeX, but I'd lose the
convenience of editing with unicode-math.
