Adding a special tag for LaTex formulas

I am prompting the model using: `\n<|grounding|>Convert the document to markdown.`
Anyway, the generated text is invalid because of the sequence `\(` not being a valid escape sequence.
The real reason is that there are no fences for the generated LaTex syntax.
Furthermore, markdown readers need the LaTeX syntax to be between `$$ ... $$` to correctly parsing the document.

The text causing the error is:
```
\(\mathrm{A} > 50\%\)
```

Would it be possible to add a special tag (i.e. <|math|> <|/math|>) to fence the LaTeX syntax?

Thanks
