title: double backslash in string
body: <p>I have the following <code>NSString</code>s:</p>
  
  <pre><code>"Test Folder\t4019-130603151520.png",
  "Test Folder\\Test sub\tNOICON"
  </code></pre>
  
  <p>I'm trying to differentiate between them based on the double backslash with this bit of code but it's not picking it up:</p>
  
  <pre><code>if (![icon rangeOfString:@"\\"].location == NSNotFound)  
  {
          NSLog(@"folder %@ contains \\", icon);
  }
  </code></pre>
  
  <p>Can anyone point out what I'm missing? Thanks.</p>
