title: How to define url which accept everykind of strings in django
body: <p>In django, I defined  url like that </p>
  
  <pre><code>(r'^checkstring/(?P&lt;string&gt;\w+)/$',views.check_str,name='check str')
  </code></pre>
  
  <p>But, When i  enter string inputs like ibrahim.yilmaz, ibrahi!m or ibrahim@ibrahim.com, it returns http 404.
  So  how can i write the url  which accept  everykind of string?</p>
  
  <p>any help will be appreciated.</p>
