I have an html-form with several text fields. 

When I try to submit not English characters (Russian in my case) server is received "unreadable" string (not questions - "???" but some strange characters). 

I simplified my code to show it here:

```
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head><title>Simple jsp page</title></head>
  <body>
    <c:out value="${param.rustext}"/>
    <form action="/test" method="post">
        <input type="text" name="rustext" width="30">
        <input type="submit" value="Submit">
    </form>
  </body>
</html>

```

How should I fix that?
