By that i mean its getting rendered in html as

This is a superscript^2

 instead of 

This is a superscript2

are you sure this supports superscript? I don’t see it on the spec:

I don’t think kramdown support superscript and subscript, unless you use html tags.

```auto
This is superscript<sup>2</sup>.

This is subscript<sub>2</sub>.

```
