title: Read a file with unicode characters
body: <p>I have an asp.net c# page and am trying to read a file that has the following charater ’ and convert it to '. (From slanted apostrophe to apostrophe).</p>
  
  <pre><code>FileInfo fileinfo = new FileInfo(FileLocation);
  string content = File.ReadAllText(fileinfo.FullName);
  
  //strip out bad characters
  content = content.Replace("’", "'");
  </code></pre>
  
  <p>This doesn't work and it changes the slanted apostrophes into ? marks.</p>
