Print a square root symbol (√) in java

Question

I am just wondering how do you print a square root(√) character in Java? I am assuming you use its unicode or something?

1) find the character; 2) copy it into the source code; 3) pray it's present in the font face where it needs to be. — John Dvorak, Mar 28 '13 at 00:32
There is a Unicode square root symbol, "\u221A". In this day and age most, but not all fonts, contain the glyph. — Devon_C_Miller, Mar 28 '13 at 01:40

Simply

System.out.println("Square Root: \u221A");

Here's the unicode number for it: http://www.fileformat.info/info/unicode/char/221a/index.htm

And this prints it out to a file for me:

package com.sandbox;

import org.apache.commons.io.FileUtils;

import java.io.File;
import java.io.IOException;
import java.text.ParseException;

public class Sandbox {

    public static void main(String[] args) throws ParseException, IOException {
        FileUtils.write(new File("out.txt"), "\u221A", "UTF8");
    }


}

When I open that file, it has the square root symbol in it.

But what is the code required to turn that into a character? — jackgerrits, Mar 28 '13 at 00:34
