ios - UITabbarItem 似乎忽略了瑞典字符

Question

我有一个从UITabBarController. 在将项目分配给标签栏控制器时，我遇到了一些标题问题UITabBarItem

class LandingVC: UITabBarController, UITabBarControllerDelegate {

override func viewDidLoad() {
    super.viewDidLoad()

    let storyboard = UIStoryboard(name: "Ssettings", bundle: nil)
    let vc1 = storyboard.instantiateViewController(withIdentifier: "bookID")
    let tab1 = UITabBarItem(title: "Föo", image: nil, selectedImage: nil)
    vc1.tabBarItem = tab1

    let vc2 = storyboard.instantiateViewController(withIdentifier: "SettingsID")
    let tab2 = UITabBarItem(title: "Sök", image: nil, selectedImage: nil)
    vc2.tabBarItem = tab2

    self.viewControllers = [vc1, vc2]
    }
}

但奇怪的是，标签栏控制器显示带有标题的项目Sok并Foo忽略瑞典字符。即使是标签栏 systemItem 似乎也失败了，任何帮助将不胜感激
