JavaScript附加HTML时出现未定义的波斯文字

Question

我在聊天项目中使用Web套接字，当通过从JavaScript附加以下代码（如以下代码）实时发送消息以查看消息时，波斯文本（如“？”）表演！

请帮助我...

public class Countries
{
    public string id { get; set; }
    public Dictionary<CountryVal, int> Data { get; set; }
}

public class Departments
{
    public string id { get; set; }
}

public class RootObject
{
    public Countries countries { get; set; }
    public Departments departments { get; set; }
}
