Hello, thank you for your PR.
Unfortunately, addition of <charCodeAt /> to the math namespace cannot be accepted because it is not valid per the HTML syntax. Specifically there is no charCodeAt element defined in the MathML Spec.

It seems that we need more namespaces and a generic way of importing from namespaces. Maybe <q cite="string/charCodeAt"></q> or something... 🤔
If you can wait for a couple of days, I will add this.

It's important to follow the HTML specifications!
Thank you for the detailed explanation.

I added Q tag instead of math.charCodeAt.

<q cite="string/charCodeAt">abc<br>0</q>

→ 97

Thank you for fast work!

However, I'd like to expect <q> to be something similar to <math>, not another function call expression. So it should be:

<abbr><q cite="string/charCodeAt"></q><br>abc<br>0</abbr>

If you don't mind, could you change the implementation like this? 🥺
