Question

I use asmack and openfire for chat application and have two problem:
Problem with offline message encoding :
user A send message to user B(is offline)
B can received offline message but when user A use Persian character user B see message like '????'.
How to detect message was sent?
I use below code to set message as sent.
below code work when I have good Internet access but some time when use poor internet access, message set as sent but doesn't sent really.
try {
connection.sendPacket(msg);
db.setMessageState(id, MessageModel.STATE_SENT);
} catch (Exception e) {
db.setMessageState(id, MessageModel.STATE_ERROR);
}
Edit:
My first problem was solved, this link may be helpful.

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());
if(offlineMsgs.containsKey(fromName))
{
offlineMsgs.get(fromName).add(m);
}else{
ArrayList<Message> temp = new ArrayList<Message>();
temp.add(m);
offlineMsgs.put(fromName, temp);
}
// ...
}
offlineManager.deleteMessages();
