// Ideally, `WM_SYSCHAR` shouldn't emit a `ReceivedChar` event
// indicating user text input. As we lack dedicated support
// accelerators/keybindings these events will be additionally
// emitted for downstream users.
// This means certain key combinations (ie Alt + Space) will
// trigger the default system behavior **and** emit a char event.
