FormComponent.setPersistent doesn't support Asian characters
------------------------------------------------------------

                 Key: WICKET-1552
                 URL: https://issues.apache.org/jira/browse/WICKET-1552
             Project: Wicket
          Issue Type: Bug
          Components: wicket
    Affects Versions: 1.3.3
         Environment: Tomcat 6.0.16, Windows 2003, JDK 6U5
            Reporter: Xiaoyu Huang


Tomcat doesn't support Control characters in cookie value. But Asian characters 
in UTF-8 do have many such characters. So if a form is going to save Asian 
characters in text field into cookies, tomcat will through an exception:

java.lang.IllegalArgumentException: Control character in cookie value, consider 
BASE64 encoding your value

So i think wicket should BASE64 encode form field values before saving to 
cookies.
