Created attachment 460395 [details] Example Xcode project Note: this is in Feedback Assistant (Radar?) as FB10401194. I'm filing it here so I can watch it in Bugzilla. If I have a @font-face declaration in CSS that specifies a custom font file and includes a unicode-range attribute and apply that font to an element that has characters both inside and outside that unicode range, the characters outside it will not render. Steps: - Run attached sample project on iOS 15. Note that the second line of text includes the English text “This is in Hebrew font. 1234.” - Run it on iOS 16. Note that the English text in the second line does not appear. If you remove the unicode-range attribute from the CSS file or remove the Hebrew characters from the second div in the html file, it works as expected. See attached screenshots for expected and observed rendering. Reproduced on an iPhone 13 Pro simulator in Xcode 14 beta 1. And on an iPad Pro 10.5” running iOS 16 developer beta 1.
