The characters associated with a key-up or key-down event.
- macOS 10.0+
These characters are derived from a keyboard mapping that associates various key combinations with Unicode characters. This property is only valid for key-up and key-down events. It raises an
NSInternal if accessed on any other kind of event object.
This property is set to an empty string for dead keys, such as Option-e. However, for a key combination such as Option-Shift-e this property is set to the standard accent ("´").
