Join error to chat with nickname

I am using openfire 3.7.0 and smack 3.2.2. I have the next simple client to join a multi user chat:

package jabber.smack;

import org.jivesoftware.smack.Chat;

import org.jivesoftware.smack.MessageListener;

import org.jivesoftware.smack.XMPPConnection;

import org.jivesoftware.smack.XMPPException;

import org.jivesoftware.smack.packet.Message;

import org.jivesoftware.smackx.muc.MultiUserChat;

public class Main {

public static void main(String[] args) throws Exception {

    XMPPConnection connection = new XMPPConnection("chat.k1.dev");

    connection.connect();

    connection.login("admin", "123123");

    MultiUserChat chatNew = new MultiUserChat(connection, "testroom@conference.chat.k1.dev");

    chatNew.join("Conj.Jardim das Acácias, bloco 19, nº 07 tЁtá");

    connection.disconnect();

}

}

I have the next problem in run this program:

Exception in thread “main” No response from server.:

Openife log have no error messages, but openfire have a session with the next nickname :
“Conj.Jardim das Acácias, bloco 19, n**o **07 tЁtá”

If I use nickname without symbol º, all ok.

Any help would be appreciated
