• WERKZEUG
• argparse
• gunicorn
• httplib2的
• itsdangerous
• twilio
• unittest2
• 的wsgiref

当我运行使用工头我的索引页面呈现精致和负载TwiML很好，但我在那里我处理短信回复/短信页面继续接收500错误，“服务器遇到内部错误，无法完成您的请求。无论是服务器超载或有错误的应用程序，“如果我推到Heroku上出现同样的错误下面是我的代码，任何想法

我是针对由Joel Franusic，为Twilio开发者倡导的解决方案。事实证明，这是一个unicode的问题。我使用的文本从其他网站形成测验。在文本中是统一的一个隐藏的撇号起源而不是预期的UTF-8，这阻止了格林独角兽从r unning。

教训教训 - 不要复制webtext，重新输入所有的，以避免错误，或者在文本编辑器或IDE，你可以分辨出两者的字体类型之间的差异用明显的字体。
