title: Regular expression validator is not allowing non-english characters for \w
body: <p>I have email field in my page, which i am validating using regular expression validator provided my asp.net. I am using same validation expression as given along with validator for emails i.e</p>
  
  <p>ValidationExpression="\w+([-+.']\w+)<em>@\w+([-.]\w+)</em>.\w+([-.]\w+)*"</p>
  
  <p>It is working fine but problem comes when I tried giving non-english letters e.g.</p>
  
  <p>è é ü û ă etc.</p>
  
  <p>But my problem is, when i use same expression in javascript it allows these characters, even at server side also same expression allows these characters.</p>
  
  <p>I think '\w' allows all alphanumeric characters as well as non english characters but
  I dont know why it is not allowing when using it in validator.</p>
  
  <p>Please suggest if I did anythig wrong.</p>
