How to put escaped curly braces inside text

[Björn Peemöller]

Hi,

is there a way to escape curly braces inside the \text command? I want

$$\text{Look at the \{braces\}.}$$

to be rendered as

Look at the {braces}.

but I get

Look at the \{braces\}.

I know that I can achieve this in MathJax by omitting the backslashes,
but I generate both a PDF via LaTeX and a HTML file from Markdown using
pandoc, so I need a result that works both for LaTeX and MathJax.

The work around I found for now is

$$\text{Look at the }\mathtt{\{}\text{braces}\mathtt{\}}\texttt{.}$$

but that is far from ideal, I think. [Issue 349] mentions the escaping
of the dollar sign, maybe it is possible to also add escaping of braces?

Regards,
Bjï¿œrn

You need to remember that MathJax is not a LaTeX and does not work in text mode. You are trying to create a really bad LaTeX and a really bad html. First, you need to look at switches in pandoc and to try to run pandoc in the modes which make good LaTeX and good html. Second, according  my experience with pandoc converting markdown files to latex cleaning resulting tex file either by some extra scripts or manually is required if one wants a decent tex file.

HTH. Victor

I agree with you that pandoc should produce correct MathML-LaTeX code,
but I won't bother if MathJax would recognize at least the following
escape sequences inside \text: \& \% \$ \# \_ \{ \}.

Note that \$ is already recognized and this change would need only three
lines to differ:

Hi Bjoern,

You might want to file a feature request on https://github.com/mathjax/MathJax/issues. Not that it means this will be implemented, but that's where clear cut feature requests should go.

Regards,

Peter.
