Is superscript possible in a plain text email?

Question

I have a plain text email that contains superscripts relating to footnotes found later in the email body.

Is this possible to use superscripts in a plain-text email, or do I have to go with html? Or, are some other symbols acceptable in this situation?

Answer 1

You'd either have to use HTML, or a format like:

This is an assertion[1] with a footnote.

[1] See? A footnote!

Answer 2

Alternatively, you could try to use Unicode superscripted numerals, but on the whole, you'd be better off with the [n] notation recommended by VoteyDisciple.
