Print a square root symbol (√) in java [duplicate]

Answer 1

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.
