Question

I am storing some french content in database but it converted to ?.

String : médiévaux, principalement pour l’anglais et le français, is converted to médiévaux, principalement pour l??anglais et le français,

I have applied utf-8 encoding to jsp page, and to the servlets as well.

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

and in servlets

response.setCharacterEncoding("utf-8");

I have also tried with decoding the string

return (string != null) ? new String(string.getBytes(), UTF8_CHARSET) : null;

and then encode it.

return (string != null) ? new String(string.getBytes(UTF8_CHARSET)) : null;

code of getting from JSP and setting it in a servlet

response.setCharacterEncoding("utf-8");
String content = request.getParameter("inputFr");
        if(content == null){
            throw new Exception("exception");
        }

        content = new String(string.getBytes(), UTF8_CHARSET);

but still the question marks appearing in the above content string. Any Help is very much appreciated.

Answer 1

The problem is that you send parameter in the URL that is not encoded. To encode it use
URLEncoder.encode(content, "UTF-8");. You can decode it in the JSP as

  <%
    out.println(java.net.URLDecoder.decode(((String[])request.getParameterMap().get("inputFr"))[0], "UTF-8"));
  %>
