i am using one servlet file, one java file, one html file as given below:

//Extraction1.jav a //java file

Code:

import java.io.IOException;
import java.net.URL;
import java.util.Scanner;

public class Extraction1 {
	
	public String toHtmlString(String url) throws IOException 
	{
		StringBuilder sb = new StringBuilder();
		   for(Scanner sc = new Scanner(new URL(url).openStream()); sc.hasNext(); )
		      sb.append(sc.nextLine()).append('\n');
		   return sb.toString();
	}

	
}

//MultiParamServl et3.java // servlet file

Code:

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class MultiParamServlet3 extends HttpServlet
{
	private static final long serialVersionUID = 1L;

	public void doPost(HttpServletRequest req,HttpServletResponse resp) throws ServletException,IOException
	{
			PrintWriter pw=resp.getWriter();
		
			resp.setContentType("text/html");
	
        	String[] values=req.getParameterValues("habits");
        		
        	Extraction1 t=new Extraction1();
    		String s=t.toHtmlString(values[0]).replaceAll("\\<.*?>","");
    		pw.println("<html><head><meta charset=\"utf-8\"></head><body>"+s+"</body></html>");
        	
	      	pw.close();
	}
}

//index.html // html file

Code:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Insert title here</title>
</head>
<body>
<form method="Post" action="MultiParamServlet3">
<Label> <br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Enter the URL :  </label>
<input name='habits' id='t2'>
<input type="submit" name="submit"> 
</form>
</body>
</html>

Servlet program able to print English text after extraction, but Hindi text converted as ????? (question mark).

If we enter URL as : "https://hi.wikipedia.or g/wiki/%E0%A4%B5%E0%A4 %BE%E0%A4%B0%E0 %A4%BE%E0%A4%A3 %E0%A4%B8%E0%A5 %80"
