  <p><code>NSString *strCrown2 = @"T-#-B-DAC";</code></p>

  <p><a href="https://i.stack.imgur.com/PbNSt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PbNSt.png" alt="enter image description here"></a></p>
  
  <p>There is \x , it is not part of string</p>
  
  <p>in console it is displaying  <strong>T-#-B-DAC</strong> it is correct </p>
  
  <p>my question is why <strong>\x</strong>  is showing there ?</p>
