Long a go I was thinking about modifying an "open" font. The idea was simply to replace the "squares" of burco, to give all control codes a consistent but distinct looking char, thus making the font usefull for the scripts editor (NOT the editbox or chat) ... but I dropped the whole idea
Something like (single chars: squares arround a small letter):
ctrl-b > [b] ... ctrl-u > [u] ... ctrl-r > [r] ... ctrl-c > [c] ... ctrl-o > [o]
One could add $chr(160) > [s] and $chr(9) > [t] as well...
