Since iOS 26.4, we are observing an issue on iPhone 13 Pro Max, iPhone 14 Pro Max, and iPhone 15 Pro Max where text is truncated on first presentation when using Bulgarian (Cyrillic) localization.
The issue affects:
- UINavigationBar title (both inline and large titles)
- UIAlertController action titles
Behavior:
- On first presentation, the text is truncated/cut off.
- On subsequent presentations, the layout appears correct.
Adding a zero-width space (\u{200B}) before the last character of the string prevents truncation. This appears to slightly increase the layout width calculation and avoids the issue.
Has anyone else encountered this behavior or found a more appropriate workaround?
