Find out how to make fonts change on the fly in X - xset fp rehash and restart
an xterm -e almost works, but not really impressively.

Add some kind of pre-processor which will make a 'go to character x' function
possible - ie. something that reads various font files and maps the offsets
of the characters.

There's a bug! Ctrl+C does not always generate SIGINT, as implied when you
press `q'.  Perhaps stty -a | awk '(/intr =/){print gensub(".*intr =
([^;]*);.*","\\1","g")}'; or would it be better to use termios? Is that
portable? :)
