Set a special string to the UILabel, but the part of string is duplicated and be strange

My user report a bug that the texts is strange and he did not taped that. So I get the texts and create a simple project, only create a label and set the texts to it. The texts is here:

【Does this sound natural?】\n \"Who's that?\" \"That's Tom when he was a kid.\" \"Do you have a same picture of Mary?

If I do not limit the number of label's line, there is no issue, but when set the number of line to 3, the text "That's Tom when occurred two times! And texts is became strange.

All code is here

class ViewController: UIViewController {
    lazy var label: UILabel = {
       let label = UILabel(frame: CGRect(x: 50, y: 100, width: 220, height: 100))
        label.numberOfLines = 3
        label.font = UIFont.systemFont(ofSize: 14)
        self.view.addSubview(label)
        return label
    }()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        self.view.backgroundColor = .lightGray
        self.label.text = "【Does this sound natural?】\n \"Who's that?\" \"That's Tom when he was a kid.\" \"Do you have a same picture of Mary?"
    }
}
