NSPredicate(format: "SELF MATCHES %@", "^[0-9A-Z]+$").evaluate(with: "126𝒥ℰℬℬ𝒢𝒦𝒮33") Returns true, and I don't know why. 𝒥ℰℬℬ𝒢𝒦𝒮 is not between 0-9 and A-Z, and why it returns true? How to avoid similar problem like this when using NSPredicate?

I have to device, one is iOS 17.0.3, the other is iOS 18.1.1. In iOS 17.0.3, everything just goes fine, but iOS 18.1.1 'didRegisterForRemoteNotificationsWithDeviceToken' and 'didFailToRegisterForRemoteNotificationsWithError' never called. I am sure I already called 'registerForRemoteNotifications' method in Appdelegate, Singning & Capabilities's Remote notification is also checked. I use Firebase, also add FirebaseAppDelegateProxyEnabled = NO in my info.plist. Someone can tell me why? Think u for ur answer.
