Google app engine GAE：如何在url中使用unicode字符

我刚刚将GAE升级到1.7.6（python 2.7）。我的应用程序在URL中使用了一些西班牙语字符（如“españa”或“cádiz”）。到目前为止，我与他们打交道没有问题。然而，升级后，我一直收到错误消息和应用程序崩溃。我在url中引入了特殊字符：

ProgrammingError('You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.',)
Traceback (most recent call last):

我编写了一个简单的应用程序来调试该问题，但没有任何积极的结果：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import webapp2

class MainHandler(webapp2.RequestHandler):
    def get(self):
        self.response.write('Hello world!')

class MyHandler(webapp2.RequestHandler):
  def get(self, param):
    self.response.write(param)

app = webapp2.WSGIApplication([
    ('/', MainHandler),
    ('/(.*)', MyHandler)
], debug=True)

访问URL“/hola”时，响应与预期一致，浏览器显示“hola”字。但是，当访问“/españa”甚至“/espa%C3%B1a”时，开发服务器会崩溃，并出现上述错误

注意，这个错误只发生在开发中，我猜它与新的sqlite数据库有关；但是，在前面的示例中，我根本没有使用数据库

有什么想法吗？求求你，救命

这似乎是dev服务器的一个bug。目前最好的办法是在GAE bug tracker:上启动bug

希望他们能更快地解决这个问题，如果更多的人“明星”它
