The JavaNativeFoundation framework is present in the arm version of macOS 14 (Sonoma). I don't have previous releases of macOS available to check. Does anyone know if JavaNativeFoundation is available in earlier arm releases of macOS?

I am not sure what you are asking, as I currently have no way to receive the character. What I would do with it is insert it into the contents of a custom text component (not a standard AppKit text component).
