Is it possible to display superscript characters in the alert() dialog?
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('2\u00B2'); shows correctly 2^2
alert('2\u00Bn'); 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" (\00B9) (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.
