title: Non breaking space doesn't work when I use join() method in Swift
body: <p>This is my custom method:</p>
  
  <pre><code>func title() -&gt; String {
      var titleComponents = [String]()
  
      for elem in 1...10 {
           titleComponents.append("my element beforenbsp\u{00a0}-\u{00a0}afternbsp)")
      }
  
      return join(", ", titleComponents)
  }
  </code></pre>
  
  <p>The result is that it breaks in places when I put <code>\u{00a0}</code>. How to solve this?</p>
