$ in math `\text{}` doesn't render

[nschloe]

Description

MWE:

$\text{$b$}$

Gitea output:

Native KaTeX output:

This is not an issue with bracket delimiters

\(\text{$b$}\)
\[
\text{$b$}
\]
```math
\text{$b$}
```

(Except for the fact math code blocks don't center the math, cf. #27602.)

Reproduce:

Then I removed all $, I got:

In GitHub:

$$\$\text{\$b\$}\$$$

↓ code

right click:

It seems that GitHub is using MathJax

@yp05327 Your accidentally added too many $ in the display-math example; it works fine there.

[yp05327]

Ah, I understanded this issue.

Do you mean that

$\text{$b$}$

and

should have same result?

[nschloe]

Almost.

$\text{$b$}$

and

\(\text{$b$}\)

should give the same result.

(When it comes to backtick math, ```math, I'm arguing in another issue report that it should be display math, not inline math. This is a whole different issue though.)

Markdown is not a strict language, we we have no strict parser for it, it's impossible to guess which $ is the real stop marker at the moment. GitHub doesn't render it either.

$\text{$b$}$

So, using non-ambiguity quotes like\(\text{$b$}\) is the best approach.

[wxiaoguang]

OK, managed to make it work by some small changes, will propose some new PRs to improve.

1.23 nightly is ready and I think it should have been fixed, feel free to take a try

[nschloe]

Confirmed fixed.
