How to output in superscript (power), example 2²?

Question

Java

You don't need to count anything, just a conclusion. I already tried to display such codes
"U+00B2", "²", "²". It does not work, it displays the same characters.

Answer 1

First make sure you have a UTF-8 encoded source file, then feel free to use any Unicode character like \u2082.

"U+00B2", "²","²"

wrong choices =)
