Special characters in URL parameters retrieved as question marks


I am posting a simple HTML form to a WebDynpro application, and then I retrieve the 2 parameters with the following code :

IWDWebContextAdapter adapter = WDWebContextAdapter.getWebContextAdapter();
String comment= adapter.getRequestParameter("comment");

Problem : some special characters (those with accents for instance) are retrieved as question marks. Their ascii character is always 65533 (unicode rather?).

I guess this is a problem of charset, but where could I change it ?

Trying to encode afterwards does not change the characters, I always get the question marks. But I may not do it the right way...

Any hint on that ?

Thanks a lot.

Best Regards,

    refer to following code.

    Stop using deprecated object IWDWebContextAdapter

    IWDProtocolAdapter adapter = WDProtocolAdapter.getProtocolAdapter();
    	try {
    		byte comment[]= adapter.getRequestObject().getParameter("comment").getBytes("ASCII");
    		String str = new String(comment);
    	} catch (UnsupportedEncodingException e) {
    		// TODO Auto-generated catch block

      Unfortunately that does not change anything. I always get these question marks, whatever charset I use (ASCII, UTF-8 or ISO-8859-1)...

      Looks like the bad conversion is done before, at the adapter level.

      Any help greatly appreciated...
