title: vertical pipe symbol not being detected in NSURL
body: <p>I'm trying to place a search in google dictionary but the url contains a vertical pipe/bar |
  My code just fails to load the site</p>
  
  <pre><code> //http://www.google.com/dictionary?aq=f&amp;langpair=en|en&amp;q=test+test+test&amp;hl=en
  
  
  if ([mySearchEngineName isEqualToString:@"Google Dictionary"]){
          NSLog(@"Currently searching %@ using %@", mySearchString, mySearchEngineName); 
  
          NSString *mutateSearchString = [mySearchString stringByReplacingOccurrencesOfString:@" " withString:@"+"];
          NSString *searchURL =[NSString stringWithFormat:@"http://www.google.com/dictionary?aq=f&amp;langpair=en|en&amp;q=%@&amp;hl=en", mutateSearchString];
          NSURL *url = [NSURL URLWithString:searchURL];
          [webBrowser loadRequest:[NSURLRequest requestWithURL:url]];
      }
  </code></pre>
  
  <p>using %7C did not work either..</p>
  
  <pre><code>NSString *searchURL =[NSString stringWithFormat:@"http://www.google.com/dictionary?aq=f&amp;langpair=en%7Cen&amp;q=%@&amp;hl=en", mutateSearchString];
