Re: How to set latex preview font to regular instead of italics?

[Mati]

I ended up with DejaVu Math TeX Gyre. You probably need this font 
installed on your system, but I'm not sure, because I had it installed 
before. Here's code to replace in my config:

  \\usepackage{mathastext}
  \\usepackage{unicode-math}
  \\setmainfont{Liberation Serif}
  \\setsansfont[Scale=MatchLowercase]{Liberation Sans}
  \\setmonofont[Scale=MatchLowercase]{Liberation Mono}
  \\setmathfont{DejaVu Math TeX Gyre}

Re: How to set latex preview font to regular instead of italics?

Ok, I found it's (La?)TeX default, specifically: By default math fonts 
are italic, and what I want is upright font. So, currently I found it 
can be done by \usepackage{mathastext} that makes italic math font a 
upright font or by using "Neo Euler" font . At the moment I succesfully 
applied it to PDF export, both mathastext and neo euler. I think I'll 
stick to Neo Euler, it's more straightforward, although Libertinus looks 
better, unfortunately it has weird SEM symbol. Maybe if other symbols 
are more straightforward I'll switch back. However, I still don't know 
how to apply those font settings to latex previews in org-mode.


I found great article on beautifying org latex export: 
https://so.nwalsh.com/2020/01/05-latex Here is my improved version of 
those export options, they might be useful for someone: (I also attach 
init.el for rest of my latex config)


One note before: You need to install Liberation font on your systems if 
you want to use it, it is used in my config. Next thing - if you want 
upright Libertine instead of Neo Euler, change some lines to this 
(you'll notice which):

  \\usepackage{mathastext}
  \\usepackage{libertinus}
  \\setmainfont{Liberation Serif}
  \\setsansfont[Scale=MatchLowercase]{Liberation Sans}

  \\setmathfont{Libertinus Math}

Credits of course go also to creators of this very nice template, I just 
improved it. In attachments there is example pdf produced with it.

It would help if you provided more details on what you tried, including
your original Org file and the screenshots.
See https://orgmode.org/manual/Feedback.html#Feedback
I also suggest reading https://www.chiark.greenend.org.uk/~sgtatham/bugs.html
