Pixel aspect ratio improves over NCBLITTER_2x2 but is less perfect than NCBLITTER_2x1, leading to slight vertical stretching. Uses Unicode sextants, left and right half blocks, and spaces. Lossy whenever more than two colors are used within a 3x2 pixel square, lossless otherwise (generalized linear interpolation is used for more than two colors). | ||

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).
