How to do superscript markup?
I wrote an answer where I needed to say "square meters". I wanted to write this as "m" followed by a superscript "2". I tried writing "m<sup>2</sup>". That worked in the preview, so I left it that way. Unfortunately, after posting the answer it was written just as "m2", not what I intended.
How to write superscripts (and subscripts while we're at it) in this system? I looked around, but couldn't find any help for the markup language, other than hover text for the button above the edit window. None of those deal with superscripts or subscripts.

I'm currently working on changing the Markdown rendering systems over to gems that support the CommonMark standard better, and which can be configured so that the post preview matches the final result.

I think those HTML tags get stripped by the server-side rendering, but I do agree that having some minimal such formatting capabilities would be helpful. <sub>, <sup> and maybe a few others would be very nice to have, especially when the full power of Mathjax isn't required for a post.

As a workaround until the markdown language uses here supports it, you could use the Unicode subscript and superscript characters, which cover a lot of mathematical and scientific uses.
I drank a glass with 200 cm³ of H₂O and felt refreshed.
