title: NSString isEqualToString: does not work. Why?
body: <p>I create an NSString using, </p>
  
  <pre><code>NSString *myString = [[NSString alloc] initWithBytes:someBuffer length:sizeof(someBuffer) encoding:NSASCIIStringEncoding];
  </code></pre>
  
  <p>I used NSLog to output myString and it displays "Hello".</p>
  
  <p>If this is the case, then why does this fail.</p>
  
  <pre><code>NSString *helloString = @"Hello"
  
  BOOL check = [myString isEqualToString:helloString];
  </code></pre>
