Mathjax does not work with chinese punctuation

Hi. The current Mathjax plugin can be quite annoying, for it only supports English punctuation.

For instance, 1+1 is ok

However，1+1 fails. This really misses the point of rendering Mathjax. This only renders Mathjax for English only.

I use Mathjax for my blog. The original Mathjax or KaTeX works well with Chinese punctuation.

I tested it, and it works as long as there are spaces before and after, see
