Quarto: Can't render greek letters in equations

Question

This Github repo, hosts a .qmd file of my dissertation template. In the last few lines of it there's an inline equation like this $Y_i = \beta_0 + \beta_1X_i + e_i$. Thing is, the greek letter \beta doesn't render.

I think may be a conflict in my preamble.tex but I couldn't figure that out.

Edit: 1 minute later I figured out that if I set a font that has greek letters, as in \setmainfont{Times New Roman} it works. I don't know what's the default Quarto font, but maybe that's it.

Answer 1

Setting a font in preamble.tex did the trick: \setmainfont{Times New Roman}
