Yes, that is exactly the kind of thing I mentioned as possibly needing updating for v4. The internals of MathJax have changed, and code in `startup.ready()` that manipulates those internals,...

What do you mean by "this possibility"?

Since you have this code in v3, you could try it in v4. When it doesn't work, you would look at the error messages and work from there. You could...

For the record this is the code updated for v4: ``` js startup: { ready() { const ParseMethods = MathJax._.input.tex.ParseMethods.default; const {RegExpMap} = MathJax._.input.tex.TokenMap; new RegExpMap('digit', ParseMethods.digit, /[\d.٫۰-۹]/); const {ChtmlMn}...

@saraOrkide: I had originally posted the v4 version [here](https://github.com/mathjax/MathJax-src/pull/new/issue3134) in response to another of your questions. Perhaps you didn't see it there.

I forgot to mention the error messages you received. That is due to having switched to CHTML output using the contextual menu. It turns out that the way exports are...

Finally, it would help us if you only include one type of problem in one issue post. Your line-break issues could all be in one, but the problem with the...
