Basically where characters are set above the top line, for example ᵃ, ᵇ, ᶜ. These
letters can be either
typeset or from
Unicode. Also for some reason
people think there'
s no superscript
i in Unicode and they replace it with ᶦ, but they know ⁿ exists when ⁱ is in the same
Unicode block as it. That's probably
unrelated, the actual information is next. So basically some examples are ¹, ², and ³ are things you might recognize from
[mathematics], but for some reason there's no superscript
pi in Unicode when we've got the superscript
golden ratio (ᵠ)? Oh yeah and there's also a
subscript one too, ᵩ. Anyways, using typesets you can make any character superscript (or subscript), but you can'
t copy and paste the
formatting, but it's cool I guess.
