Using latex in suffixes

Is there a way to type latex in suffixes for the math input?
I just need the suffix to say cm² - but it’s rendering as cm^2

Should work with backticks, and exponents use curly braces:

suffix: `cm^{2}`

That’s what I thought, but it renders as `cm^{2}` (i.e. the latex notation seems to be ignored)

This worked for me. I believe it’s just using the unicode character.

suffix: "cm²"
