【问题描述】：
我刚刚将 GAE 升级到 1.7.6 (python 2.7)。我的应用在 URL 中使用了一些西班牙语字符（例如“españa”或“cádiz”等词）。到目前为止，我与他们打交道没有任何问题。但是，升级后，每当我在我的网址中引入特殊字符时，我都会收到错误消息并且我的应用程序崩溃：
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问题，但没有积极的结果：
#!/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)
当访问 URL“/hola”时，响应如预期，浏览器显示“hola”字样。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，我猜是和新的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？请帮忙！
