### Bug description

I've got a Jupyterlab notebook that I'm using to write a report.  It uses greek letters (in particular μ).  These show up correctly in JupyterLab (and also in the ipynb file if I open it in an editor using utf-8 encoding).  However, when quarto converts to a PDF, the μ character is missing (it appears as a blank) and if I set `keep-tex: true`, the (seemingly utf-8 encoded) `.tex` file includes a different character in place of the μ: ¿.

I can work round it with things like `$\mu$`, although that puts the μ in italics (even if I use `\mathrm`), which is undesirable.

I've attached a very simple `.ipynb` file, along with the generated `.tex` and `.pdf` files that are produced when running `quarto render MuTest.ipynb`.

I am using Windows 10.  I am not using R at all, so haven't ticked the checklist box associated with RStudio.

### `quarto tools check` Output

```bash
> quarto tools check
(|) Reading Tool DataSending fatal alert BadCertificate
[>] Reading Tool Data
ERROR: TypeError: error sending request for url (https://api.github.com/repos/yihui/tinytex-releases/releases/latest): error trying to connect: invalid peer certificate contents: invalid peer certificate: UnknownIssuer
```

(this is probably due to the corporate zscaler proxy, which replaces SSL certificates and generally makes things difficult...)
