Is it possible to display superscripted characters (not only numbers) in the alert(), confirm() or prompt() dialogue boxes in JavaScript?

Due to some reasons I need to insert a text:

2 followed by superscripted 'n'
2^n

Into JavaScript alert, confirm and prompt boxes. Fast google searching did help but not exactly I found a way to display superscripted numbers in dialogue boxes using Unicode u00B character but it doesn't work with characters

alert('2u00B2'); shows correctly 2^2

alert('2u00Bn'); shows 2u00Bn

So the goal is to show a character superscripted not the number.

^ is used as Power and to show that next character is superscripted, just in case someone gets confused.

There's nothing magical about that character code - it just happens to be the one picked for the Superscript two character. There's also a Superscript three (u00B3) (³) a Superscript one (0B9) (¹), and a Superscript Latin Small Letter N (u207F) (ⁿ). But if you need some other superscript, you're out of luck - alert() doesn't render HTML, so you're limited to the characters defined by Unicode.

You might be better off abandoning alert() entirely, and simulating a modal dialog within the page itself. Many libraries exist to provide this functionality already, including the excellent jQuery UI Dialog.
