How to write UTF-8 encoded data into a file – Java

Here’s the Java example to demonstrate how to write UTF-8 encoded data into a text file – “c:\\temp\\test.txt”

P.S Symbol “??” is some “UTF-8″ data in Chinese and Japanese

package com.mkyong;
 
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;
import java.io.Writer;
 
public class test {
	public static void main(String[] args){
 
	  try {
		File fileDir = new File("c:\\temp\\test.txt");
 
		Writer out = new BufferedWriter(new OutputStreamWriter(
			new FileOutputStream(fileDir), "UTF8"));
 
		out.append("Website UTF-8").append("\r\n");
		out.append("?? UTF-8").append("\r\n");
		out.append("??????? UTF-8").append("\r\n");
 
		out.flush();
		out.close();
 
	    } 
	   catch (UnsupportedEncodingException e) 
	   {
		System.out.println(e.getMessage());
	   } 
	   catch (IOException e) 
	   {
		System.out.println(e.getMessage());
	    }
	   catch (Exception e)
	   {
		System.out.println(e.getMessage());
	   } 
	}	
}
