title: Should I support Unicode in passwords?
body: <p>I would like to allow my users to use Unicode for their passwords.</p>
  
  <p>However I see a lot of sites don't support that (e.g. Gmail, Hotmail).</p>
  
  <p>So I'm wondering if there's some technical or usability issue that I'm overlooking.</p>
  
  <p>I'm thinking if anything it must be a usability issue since by default .NET accepts Unicode and if Hotmail--er, the new Live mail--is built on that, I don't see why they would restrict it.</p>
  
  <p>Has anyone encountered similar issues?</p>
