title: Escape fullstop before slash in URL string
body: <p>I've found an oddity I'm trying to get around with C# sanitizing / interfering with a specified URL, and giving a 404 as a result.</p>
  
  <p>It happens where there's a forward slash after a full-stop - C# and Visual Studio are determined to remove the fullstop. </p>
  
  <p>For <strong>Visual Studio</strong>, this is the Control-click from a string linking to the mal-formed URL</p>
  
  <p>In <strong>compiled C#</strong> the string is transformed, even before getting to new URI().</p>
  
  <p>The link is:</p>

  </blockquote>
  
  <p>(It's the './' at the end that causes the issue)</p>
  
  <p>I've tried escaping both the fullstop + slash in ASCII, and the 'dontEscape' option in the Uri() constructor, but no luck so far...</p>
  
  <p>And other thoughts as to how I can get this string to allow the correct URL?</p>
  
  <p>Thanks.</p>
