Idle runs code in an environment that is slightly altered from the 
standard python startup environment'.  idlelib.IOBinding has this
'''
# Try setting the locale, so that we can find out
# what encoding to use
try:
     import locale
     locale.setlocale(locale.LC_CTYPE, "")
'''
idlelib.run, which runs in the user-code subprocess, imports IOBinding. 
Setting LC_CTYPE is sufficient for getlocale() to not return null values.

C:\Users\Terry>python -c "import locale; print(locale.getlocale())"
(None, None)

C:\Users\Terry>python -c "import locale; 
locale.setlocale(locale.LC_CTYPE, ''); print(locale.getlocale())"
('English_United States', '1252')
