You've lived a sheltered life! For control characters Ive seen: - garbage (the ASCII equiv of mojibake) - Straight ^A^B^C - Maybe their names NUL,SOH,STX,ETX,EOT,ENQ,ACK… - Or maybe just a little dot . - More pathological behavior: a control sequence putting the terminal into some other mode But I dont ever remember seeing a control character become invisible (except [ \t\n\f]) -- https://mail.python.org/mailman/listinfo/python-list
