Checking a little -

The python package for curses does not use the curses function unctrl(),
and uses this chunk instead:

def unctrl(c):
    bits = _ctoi(c)
    if bits == 0x7f:
        rep = "^?"
    elif bits & 0x20:
        rep = chr((bits & 0x7f) | 0x20)
    else:
        rep = "^" + chr(((bits & 0x7f) | 0x20) + 0x20)
    if bits & 0x80:
        return "!" + rep
    return rep

(that accounts for the odd format of the output).
