How to simulate UTF-8 encoded request parameters

Hi all,

I'm new to the list (although not new to HttpUnit) and couldn't figure
out a mail archive with convenient searchability. So sorry, if this
has been discussed before.

My team is in the middle of converting a reasonable big web
application from ISO-8859-1 to UTF-8-encoding. Now, the incoming
requests start to be URL-encoded using character set UTF-8. we
configured the servlet container (tomcat here) to handle those
requests properly, which works fine.

Coming to the point, though, I ran into issues trying to unit test
some servlet using HttpUnit. the servlets read request parameters. Of
course I want to simulate UTF-8 encoded parameters here. But couldn't
get it the right way - if there is one.

The TestCase I'll attach fails with "ComparisonFailure: expected:
<äöü> but was: <äöü>". Could somebody please point me into a
direction of howto unit test those scenarios the right way?

Any hints are highly appreciated! Thanks in advance

ps: here comes the code:

import java.io.IOException;
import java.net.MalformedURLException;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

import junit.framework.TestCase;

import com.meterware.httpunit.GetMethodWebRequest;
import com.meterware.httpunit.HttpUnitOptions;
import com.meterware.httpunit.WebRequest;
import com.meterware.servletunit.InvocationContext;
import com.meterware.servletunit.ServletRunner;
import com.meterware.servletunit.ServletUnitClient;

public class HttpUnitTest extends TestCase {

	/**
	 * Trying to figure out, how to simulate UTF-8-encoded request parameters
	 *
	 * @throws MalformedURLException
	 * @throws IOException
	 */
	public void testURIEncoding() throws MalformedURLException, IOException {
		// Thought, this would simulate a containers URIEncoding-setting
		HttpUnitOptions.setDefaultCharacterSet("utf-8");
		
		ServletRunner servletRunner = new ServletRunner();
		servletRunner.registerServlet("dummy", DummyServlet.class.getName());

		WebRequest request = new GetMethodWebRequest("http://localhost/dummy");
		request.setParameter("param", "\u00e4\u00f6\u00fc");
		
		ServletUnitClient sc = servletRunner.newClient();
		InvocationContext ic = sc.newInvocation(request);
		HttpServletRequest httpRequest = ic.getRequest();
		
		// Test fails with "ComparisonFailure: expected: <äöü> but was: <äöü>"
		assertEquals("äöü", httpRequest.getParameter("param"));
	}
	
	class DummyServlet extends HttpServlet {
		
	}
}
