Netbeans GUI editor doesn't like ASCII

So I'm making a basic GUI with the NetBeans IDE (in Java), and I want to make a button with a √ sign in it. It didn't let me copypaste it in, so I tried using its ASCII code:

Instead of the square root sign, however, it gave me "û", and I have no idea why. Can someone please explain why this is happening, as well as offer an idea as to how I should go about this?

That isn't ASCII. The ASCII code only goes from 0 to 127.

But on the other hand Java doesn't use ASCII. It uses Unicode, which goes from 0 to 65535. Even though it has done that since it was first invented in 1995, the word doesn't seem to have got out to people who only use the English alphabet on a daily basis.

So your 251 is the Unicode 251. That's a decimal number, its hexadecimal equivalent is FB so you'll find it on this page from the Unicode code charts. As you'll see from that chart (scroll down a bit) its Unicode name is "LATIN SMALL LETTER U WITH CIRCUMFLEX", and that's what you are seeing.

I have no idea why you would expect to see a square-root sign. See here for information about that.
