[IPython-user] [IPython-dev] Win32 - call for pyreadline testing

[Jörgen Stenarson]

Tom thanks for the report. I have just comitted a patch I think works 
around this, please let me know if it fixes your problem. The problem is 
that doctest replaces sys.stdout with a dummy object before it imports 
pdb which imports readline, this dummy object does not preserve the 
encoding property of the original stdout. Since doctest  is in the 
process of being imported I don't see how we can obtain the original 
stdout and set a proper encoding so we assume ascii. If you really need 
a correctly set output encoding import readline before doctest.
