http://www.mail-archive.com/jetspeed-user%40jakarta.apache.org/msg12954.html

*There can be you will answer?
ADDITION INFO:
after including into <form ...> additional attribute:  
accept-charset="ISO-8859-1"
national characters receive is correct! But only from Mozilla-client or 
Opera-client.
From MS IE 6 (I dont have IE 5.5) - without changes 8(((( - I receive 
broken chars....

I find method DefaultJetspeedParameterParser.getString(String name), 
which breaks the coding:
ORIGINAL:  
public String getString(String name)
   {
       String str = super.getString(name);
       if (str == null) return null;

       try
       {
           return new String(str.getBytes("8859_1"), 
getCharacterEncoding());
       }
       catch (Exception e)
       {
           logger.warn("DefaultJetspeedParameterParser: Exception: " + 
e.toString());
           return str;
       }

   }
MY MODIFICATION:
       try
       {
           //from Opera - exception, but on in&out - characters correct
           //from Mozilla - in - correct, out - correct
           //from IE 6 - in INCORRECT, out - correct
           return new String(str.getBytes(), getCharacterEncoding());
       }
