Zendesk iOS  MessagingController doesn't support Keybord “Chinese Traditional Zhuyin”

Zendesk iOS Tech Supporters

When  invoking the MessageViewController in Zendesk iOS SDK，We had som problems： It seems that messagingViewController can’t support  Keybord “Chinese Traditional Zhuyin” on iPhone 

I present MessagingViewController with the function below

    func show(rootViewController: UIViewController?) {

        guard let messagingViewController = Zendesk.instance?.messaging?.messagingViewController() else { return }

        self.configureGlobalNavibarStyle();

        let navi = UINavigationController(rootViewController: messagingViewController);

        rootViewController.present(navi, animated: true, completion: nil)

        print("\(self.TAG) - show")

    }

Now,We can’t input Chinese Word with Keyboard   “Chinese,Traditional Zhuyin”.

When we typed with keyboard “Chinese,Traditional Zhuyin”, only the letter could be input ,but we expect we can spell Chinese Word and Input.
