Xcode 11.3 external fonts

Just upgraded to Xcode 11.3 and it doesn't want to retrieve a high-integer character from an external font: FreeSerifBold.otf. I used that font because it has musical notes and rests and other symbols, which I have laboriously arranged into a Percussion Staff for my app. Every musical symbol in my display has been replaced by a '?' in a rounded rect.


According to https://unicode-table.com/en/1D160/, NSString *sN8 = @"\U0001D160"; should result in an eighth note. Instead, it shows as an unknown, a '?' displayed to the debugger.


Is Apple discouraging external fonts, trying to get developers to use the new SF Symbols paradigm? Or is this just a bug?
