UnicodeMathML
JavaScript-based translation of UnicodeMath to MathML that can be integrated into arbitrary HTML or Markdeep documents. An interactive "playground" allows for experimentation with the syntax and insight into the translation pipeline.

InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
There's also Temml (a lightweight fork of KaTex).

Both ± and √ have been on Mac keyboards, if you hold down the Option key, since probably 1984. Using ² instead of ^2 doesn't give me the same output, though.
A Typst Unicoderator could make this transformation for you, but I don't think one's been written yet. An automatic linebreaker à la Prettier sounds like an even more difficult challenge.
There's UnicodeMath, defined at <https://www.unicode.org/notes/tn28/UTN28-PlainTextMath-v3.2....> and <https://unicodemath.org> says there's a UnicodeMath to MathML converter at <https://github.com/MurrayIII/UnicodeMathML/tree/main>. All UnicodeMath seems to get you over Typst in this instance is superscript support.
If you're going to send out math as SVGs anyway, you can also just use your normal latex to PDF renderer (e.g. pdflatex) on each formula, and then convert the output PDFs to SVGs. That way, you get the same output you'd get with latex, and you can also use latex packages that aren't supported by MathJax (e.g. tikz-cd). I've prototyped a latex to html converter [1] based on that approach, but it's probably not ready for serious use. Here's an example: https://www.mbid.me/lcc-model/

Mathstodon ( https://mathstodon.xyz/about ) integrates this, forking/extending Mastodon to support inline LaTeX in Mastodon posts and equations, which get rendered by MathJax on the client side. I think that's neat.
- "This is important, since several math-based instances exist (such as https://mathstodon.xyz ,https://types.pl) and produce math-based posts. However, when these posts federate to other instances they cannot be rendered, since other instances do not have MathJAX installed. Thus, a more portable version based on open standards is necessary."

> Could you elaborate on why you switched away from it?
I started using KaTeX sometime after 2015 because it promised to be fast (the fastest! [1]). I had to change the representation of a bunch of expressions because KaTeX didn't support some environments, whilst MathJax did. It was a trade-off I was willing to accept at the time.
Many years later, I started writing a personal static-site generator. I wanted comparatively lightweight pages, so rendering server-side was an option. I re-evaluated MathJax vs KaTeX again and this time I leaned towards MathJax, as speed was no longer an issue for me. It looks like KaTeX has broader support now [2].
