java jar writes in two different character encoding

So my code is working fine when running from Eclipse, but executing the project's runnable jar does not.

Here is my code:

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.nio.file.StandardOpenOption;
import java.util.ArrayList;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import java.util.stream.Collectors;


public class cc {

    public static HttpURLConnection con;
    public static String url = "http://bac.onec.dz/index.php";
    public static int begin;
    public static int max;
    public static boolean paused=false;
    public static String path="result.csv";

    public static void setData(int b,int m){
        begin=b;max=m;
    }
    public static void main(String[] args)  throws Exception {
            int i =1;
            setData(35043487,2);
            while (i<=max && !paused) {
            sendPost(begin++);
            i++;
        }
    }

    private static void sendPost(int mat) throws Exception {
        String urlParameters ;
        URL obj = new URL(url);
        BufferedReader in;
        StringBuffer response;

        con = (HttpURLConnection) obj.openConnection();
        con.setRequestMethod("POST");
        con.setRequestProperty("Host", "bac.onec.dz");

        con.setDoOutput(true);
        urlParameters = "matriculebac="+mat+"&dobac=%D8%A7%D8%B3%D8%AA%D8%B8%D9%87%D8%A7%D8%B1+%D8%A7%D9%84%D9%86%D8%AA%D9%8A%D8%AC%D8%A9";

        DataOutputStream wr = new DataOutputStream(con.getOutputStream());

Running from eclipse, the output file is perfect with UTF-8 encoding.

Running from exported jar, a part of the output file is in ANSI encoding. Now that wouldn't be a problem if I'm writing just these words, but the code writes other content in Arabic, and the output be like

Output file was opened with Notepad++ in ANSI http://i.stack.imgur.com/6RGEj.png in UTF-8 http://i.stack.imgur.com/Li0qf.png

As I mentioned this problem hasn't encountered when running from eclipse
