 Return a string representation of the ASCII character c. If c 
is printable, this string is the character itself. ... 
from curses.ascii import unctrl 
>>> unctrl('a') 
>>> unctrl('A') 
unctrl() is not working for the full printable charset. 
The Q&D fix is: 
def unctrl(c): 
+    if isprint(c): 
+    	return c 
    bits = _ctoi(c) 
    if bits == 0x7f: 
This bug has been confirmed in python 2.3 and 2.2 as 
distributed in Debian Linux.

The breakage seems to run a bit deeper than that; characters >127 also 
have problems.  I've attached a revised patch that seems to fix all the 
problems.  This patch has been checked into the trunk, and I've also 
added some simple unit tests that would have caught the problem.
