* Generate Ctrl-C events by calling GenerateConsoleCtrlEvent.
I noticed that calls to this routine don't behave exactly the same as
a real Ctrl-C keypress. In Python, pressing Ctrl-C immediately
displays a new "KeyboardInterrupt" line. Calling
GenerateConsoleCtrlEvent has no immediate effect, but after pressing
Enter, Python displays a stack trace where a KeyboardInterrupt was
raised. After some testing, I suspect the issue is that a real Ctrl-C
keypress interrupts a blocking console read, but
GenerateConsoleCtrlEvent does not.
I also tried synthesizing Ctrl-C using (a) PostMessage with
WM_{CHAR,KEYDOWN}, and (b) SendInput. I couldn't get either to work.
* Recognize ESC sequences. The set of recognized sequences is ad hoc.
* Recognize UTF-8-encoded characters and convert them to UTF-16.
* The code currently uses a timeout to differentiate between pressing ESC
and pressing a key that generates an ESC sequence. I have a theory that
I can use the "Device Status Report" ESC sequences to avoid this
timeout.
