Weird parsing problem with inline asciimath

Development
1

Hi !
I'm trying to add a simple asciimath (http://asciimath.org/) implementation to Joplin. I proceeded by first duplicating the katex.js rule and adding my new file (asciimath.js) in MdToHtml.js.

Asciimath blocks works like a charm but inline math seems to be ignored, and i can't find where i broke it...

Here is the diff (katex.js/asciimath.js)

If you're up to help me and you need more informations i'll be glad to provide it :smiley:

Inline only works with few characters it seems. With the % sign for example, it works. Code
I think it's markdown-it parser that's making that restriction.
