Unicode的Django的URL參數

Question

我現在有這個URLPATTERN：

from __future__ import unicode_literals 
from django.confs.urls import url 
from django.utils.encoding import python_2_unicode_compatible 
from . import views 

app_name = 'bans' 
urlpatterns = [ 
    url(ur'^(?P<region>.*)/(?P<summoner_name>.*)/$', views.get_user, name='bans'), 
] 

然而，當URL有一個像 'A' 向UTF-8字符，它給了我一個錯誤：

'ascii' codec can't encode character u'\xe5' in position 40: ordinal not in range(128) 

值越來越設定的用戶名變種是：

u'k\xe5re%20j\xf8rgen' 

以上應該說「卡蕾約爾根」。

網址不能包含Unicode字符。瀏覽器應該百分比轉義字符串，並將其作爲ascii發送。如果你的正則表達式不是一個unicode字符串，事情應該會起作用，儘管當你得到你的名字變量時，你必須對它進行百分比解碼。
