Answer 1

res.setContentType("text/html; charset=UTF-8");
PrintWriter out = new PrintWriter(
                         new OutputStreamWriter(res.getOutputStream(), "UTF8"), true);

also you can check encoding type

String encoding = request.getCharacterEncoding();
            if ((encoding != null) && (encoding.equalsIgnoreCase("utf-8")))
            {
                response.setContentType("text/html; charset=utf-8");
            }
