上一个（％）命令在Rivescript游乐场测试中引发错误？

Question

我正在Rivescript上创建一个约会应用聊天机器人，并尝试使用％previous命令来触发有关安排日期的条件性主题，但是当我尝试使用％previous命令时，我得到了附加的错误消息，通知我不能将％用作触发器。

这是我得到的错误：Error in your RiveScript code: Syntax error: Triggers can't contain uppercase letters, backslashes or dots in UTF-8 mode at stream() line 186 near % thats funny. wanna hang out sometime?我在这里使用'Rivescript Playground'：https://play.rivescript.com/-为了方便起见，我粘贴了下面的相关代码，但错过了替代方法< / p>

+ hello
- hey!{weight=5}
- hey cutie{weight=2}
- hey ur cute{weight=1}
- hey ur cute, wanna go on a date?{weight=1}

+ hey
@hello

+ yo
@hello

根据错误消息和GoDoc文档，您不能在UTF-8模式下使用圆点。

  

语法错误：触发器不能包含大写字母，反斜杠或   UTF-8模式下的点

由于触发字符串包含一个点而引发错误。

% thats funny. wanna hang out sometime?
