Hints on injecting input into Windows (use 'ScanCode' for Unicode!)

 Use ScanCode to inject Unicode characters!

Got a Unicode string and need to inject it using the InputInjector class? Wondering how to inject it since the InjectedInputKeyboardInfo class has a ScanCode and a Virtual Key but no Unicode char? It turns out to be easy!

In the InjectedInputKeyboardInfo class, set the KeyOptions to Unicode and then fill in the ScanCode with the unicode char. Since you've got a string, you'll make a list of InjectedInputKeyboardInfo items and then send them all with the InjectKeyboardInput method.

I know this works because my new keyboard will happily inject  Unicode strings like this: 😋👩‍👩‍👧‍👧!
