语音AI帮助Unicode无法调用

Question

一直说无法调用unicode，我该如何解决？

这是我要执行的代码

if 'weather forecast in' in command:
        reg_ex = re.search('weather forecast in (.*)', command)
        if reg_ex:
            city = reg_ex.group(1)
            weather = Weather()
            location = weather.lookup_by_location(city)
            forecasts = location.forecast
            for i in range(0,3):
                talkToMe('On %s will it %s. The maximum temperture will be %.1f degrees.''The lowest temperature will be %.1f degrees.' % (forecasts[i].date(), forecasts[i].text(), (int(forecasts[i].high())-32)/1.8, (int(forecasts[i].low())-32)/1.8))

我使用的是Mac，因此终端告诉我Unicode无法调用。

我在终端收到的错误消息

    Traceback (most recent call last):

    myCommand()
