Java Firebase的多字节值

我需要在Firebase中存储多字节字符串，如áćěěž。当我使用JavaScriptAPI时，它可以工作，并且字符串áćěž在Firebase中。但是当我在Java ref.setValueáćěěž中尝试它时；它不起作用。没有错误消息，但Firebase将我的客户端设置为已断开连接，但未触发onDisconnect方法

我的servlet代码是：

 @SuppressWarnings("serial")
 @WebServlet(urlPatterns = {"/server/*", "/set/*"})
 public class FbServlet extends HttpServlet {

        private final Firebase ref = new Firebase(FbRef.refD + "xx");

        @Override
        protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
            ref.child("first").setValue("work"); //this is the first time okey
            ref.child("nowork").setValue("áčšěž"); //this do not work and after this command firebase do not work
            ref.child("last").setValue("dontwork"); //this do not work 

        }

    }

我在WildFly 8和Tomcat 7.0.41上进行了尝试。我正在使用JDK1.7、maven和WindowsXP

然后我尝试将它推到Openshift WildFly 8，它可以工作，但写下了？？？？？：

所以我的问题是，是否有办法做到这一点？转义字符串，或者类似的东西

你能发布你正在使用的代码和你正在运行的平台吗？我能够设置上面的值，然后通过ValueEventListener在OS X上使用最新的Java客户端和Java 1.7将其取回。@GregSoltis我更新了我的帖子。谢谢你的回复。谢谢你的更新，我会看看是否可以重现。我仍然无法重现这个错误。日志中是否有可能抛出异常？能否添加：Firebase.getDefaultConfig.setLogLevelLogger.Level.DEBUG；到应用程序的开始并发布日志输出？@GregSoltis我更新我的发布添加日志输出。没有例外。
