void Start () {
		LuaEnv env = new LuaEnv();
        env.AddLoader(MyLoader);
	    env.DoString("require 'fish'");
	}

    byte[] MyLoader(ref string pathfile)
    {
        string absPath = @"E:\ProjA\LUALearn\" + pathfile + ".lua.txt";
        return System.Text.Encoding.UTF8.GetBytes(File.ReadAllText(absPath));
    }

坑：

lua编码使用UTF8编码格式
