A few weeks ago I built a function to read keystrokes from the keyboard. (In machine code, of course.) I planned to support just ASCII keys to begin.

Today I tried to force myself to work on the rest. Terminal escape sequences like arrow keys, UTF-8, and somehow distinguishing between the two.

Surprise: both were already working! I just had to read 32 bits rather than 8 from stdin. Legal UTF-8 doesn't conflict with terminal escapes in 32-bit space.
