Greek letters not rendering in math mode when rendering to pdf

DrEntropy commented 1 year ago

Bug description

(bold) Greek letters in math mode are not rendering when I render documents to pdf, even though they render fine to HTML. Not sure if this is related to this: https://github.com/quarto-dev/quarto-cli/issues/3013 as that had to do with unicode in Julia.

Note that if I render the intermediate .tex file myself it renders fine, which is odd. (However the greek letters are not bold faced in the render, I have just learned this is expected)

Steps to reproduce

To reproduce:

Open visual studio code
Create a new quarto book project.
In the boilerplate code, simply add something like this:
```
$$
\mathbf{\theta}
$$
```
Render to html: No problemo
```
quarto render --to pdf
```
No theta!

Expected behavior

Greek letter should render.

Actual behavior

Blank where the greek letter should be.

Your environment

I tested this on Mac and Windows. Windows was using tinytex, Mac was using TexLive.

I updated texlive on the mac and now it is working, except not \mathbf{\theta}. That still gives a blank. I edited the original but since this is probably a tex issue and not a quarto issue I should probably close this.

Hmm, quarto render to pdf works fine with \boldsymbol instead. Problem exists between keyboard and chair, closing this !

Just to clarify, the issue here is that there's no way for us to know, from Quarto, which fonts will have the glyphs necessary to render the output generated by pdflatex.

Tangentially, this is something that typst gets fundamentally right that the latex ecosystem simply doesn't have the foundation to do: https://typst.app/docs/reference/text/text/#parameters-font In typst, you specify the a list of fonts for a block of text, and typst will go down the list of fonts, only picking it if all glyphs are present.
