I’m using a simple template with KaTeX and the following fails:
$$\mathcal I := { X\subset E : \text{the vectors in $X$ are linearly independent} }.$$
I suspect this is due to Hugo automatically replacing { → {, and I check this by testing $a\_{b}$.
How can I go around this, so that my LaTeX code also works on other markdown parsers that do not do this replacement?

Going to bump this. To summarize, `\{` is being replaced with `{`, probably due to HTML escaping.

I recently got a contribution to my [Zen theme](https://github.com/frjo/hugo-theme-zen) that implements KaTeX. Tested your example and it seems to work just fine. At least it renders the same way as it does on [https://katex.org](https://katex.org).
If you post a link to your repo we can check what the difference are.

I’ve tested it on your repo: it has the exact same issue. You can try the following examples:
```auto
$$\{\text{this should have braces!}\}$$
$${A}_B C_{D}$$
```

Not sure what causes the problem without seeing your codes, the result of the [KaTeX module](https://hugomods.com/en/docs/content/katex/) seems work as expected.
````markdown
```katex
\mathcal I := { X\subset E : \text{the vectors in $X$ are linearly independent} }.
```
```katex
\{\text{this should have braces!}\}
```
{{< katex >}}
{A}_B C_{D}
{{< /katex >}}
````

Thanks for the response. This would not work for my setup, which instead just imports KaTeX directly - that supports my usage of `$...$` and `$$...$$` for any equations.
I’m having some progress by manually doing some transforms on the `.RawContent`. Something like:
```auto
{{ $content := .RawContent }}
{{ $content = $content | replaceRE "\\\\\\\\" "\\\\\\\\" }}
{{ $content = $content | replaceRE "\\\\{" "\\\\{" }}
{{ $content = $content | replaceRE "\\\\}" "\\\\}" }}
{{ $content = $content | replaceRE "\\_\\{" "\\_{" }}
{{ $content = $content | replaceRE "\\_\\\\" "\\_\\" }}
{{ $content | .Page.RenderString | safeHTML }}
```
and then calling this partial in `single.html`.

Perhaps this is the cause, you can check the generated HTML source code (CTRL+U on Chrome) to diagnose. KaTeX works with the `.Content` properly.

Yes, but what I am trying to do is to _avoid_ the use of a custom shortcode. Anyway, this approach worked out fine.
