오프라인 메시지가 ???? , aSmack과의 Openfire

Question

난 채팅 애플리케이션 asmack과의 Openfire 사용하고있는 두 가지 문제점 : 오프라인 메시지 인코딩

1. 문제점 :

   • 사용자 A가 사용자 B에게 메시지를 보내는 (오프라인)
   • B는 오프라인 메시지를 수신 할 수 있지만 사용자 A가 페르시아어 문자 사용자 B를 사용하면 '????'와 같은 메시지가 표시됩니다.
2. 메시지를 어떻게 탐지 했습니까?

다음 코드를 사용하여 보낸 메시지를 설정합니다. 아래 코드가 작동하지만 인터넷 접속이 좋지 않을 때 가끔 인터넷 접속을 사용할 때 보낸 메시지가 실제로 전송되지는 않습니다.

try { 
    connection.sendPacket(msg); 
    db.setMessageState(id, MessageModel.STATE_SENT); 
} catch (Exception e) { 
    db.setMessageState(id, MessageModel.STATE_ERROR); 
} 

편집 : 내 첫 번째 문제는 해결되었다

configureConnection(ProviderManager.getInstance()); 
      OfflineMessageManager offlineManager = new OfflineMessageManager( 
       connection); 
      int count = offlineManager.getMessageCount(); 
        Iterator<Message> it = offlineManager.getMessages(); 
         while (it.hasNext()) { 
           Message m = it.next(); 
           String fromName = m.getFrom(); 
           //Date currentDate = new Date(); 
           String text = m.getBody() + " (offline)"; 
           if(fromName.contains("/Smack")){ 
            fromName = fromName.replace("/Smack",""); 
           } 
           Log.i("offile chat message with user name ",text+" username "+fromName); 
           dbHelper.addmessageUser(fromName, text, "0", "1",""+System.currentTimeMillis());
