我剛剛將GAE升級到1.7.6（python 2.7）。我的應用在網址中使用了一些西班牙文字符（如「españa」或「cádiz」）。到目前爲止，我沒有遇到任何問題。然而，升級後，我keed有和錯誤消息，我的應用程序崩潰wenever我在URL引進特殊字符：GAE：如何在url中使用unicode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.',)

我寫了一個簡單的應用程序調試問題，沒有陽性結果：
#!/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)
訪問URL「/ hola」時，響應與預期相同，瀏覽器顯示「hola」字。但是，在訪問「/españa」或甚至「/ espa％C3％B1a」時，開發服務器會崩潰，並顯示上述錯誤。
請注意，錯誤只發生在開發中，我猜它與新的sqlite數據庫有關;然而，在前面的例子中，我根本沒有使用數據庫！
任何想法？請幫忙！
