string in double $ will convert to MathJax when using pandas Dataframe

[176coding]

string in double $ will convert to MathJax when using pandas Dataframe, just as the image show:

my df contains string 'from $100 some string here $1000', but when I show it in notebook, it will convert to MathJax and the font has changed

@mpacer Any thoughts?

Hmmm… That's why there's supposed to be a rule around mathjax that you don't treat \s$\d as a ending delimiter.

I can confirm that this is also present in markdown cells. The simplest solution is to just escape the $ with \$ so that it would be written as 'from \$100 to \$1000'.

But this shouldn't be happening regardless. It's likely related to how delimiters are specified… this goes back to at least 4.0 so I don't think it was recently introduced.

However fixing this is probably going to break people's notebooks because it will be enforcing a stricter approach to parsing mathjax which other people may have been relying on.

Would this require a fix in notebook? Or mathjax? Or ipython?

It would be nice if we could fix this and display a warning in the output for cases like this one where the user may be trying to display math using slightly unexpected delimiters.
