	Notcurses provides input from keyboards and mice. Single Unicode codepoints are received from the keyboard, directly encoded as <tt>char32_t</tt>s. The input system must deal with numerous keyboard signals which do not map to Unicode code points. This includes the keypad arrows and function keys. These "synthesized" codepoints are enumerated in <tt>notcurses.h</tt>, and mapped into the [https://unicode.org/charts/PDF/U100000.pdf Supplementary Private Use Area-B] (U+100000..U+10FFFD). Mouse button events are similarly mapped into the SPUA-B.		Notcurses provides input from keyboards and pointers (mice).
