Check sys.stderr.errors attribute. Try
>>> import sys
>>> x = '\u2119'
>>> x.encode(sys.stderr.encoding, sys.stderr.errors) # succeed
>>> x.encode(sys.stdout.encoding, sys.stdout.errors) # fail
sys.stderr uses 'backslashreplace' error handler that is why you see
\u2119 instead of ℙ.
On Linux with utf-8 locale:
>>> print('\u2119')
ℙ
>>> print(repr('\u2119'))
'ℙ'
>>> print(ascii('\u2119'))
'\u2119'
>>> '\u2119'
'ℙ'
>>> repr('\u2119')
"'ℙ'"
>>> ascii('\u2119')
"'\\u2119'"
On Windows, try https://pypi.python.org/pypi/win_unicode_console
C:\> pip install win-unicode-console
C:\> py -i -m run
It is alpha but your feedback may improve it
https://github.com/Drekin/win-unicode-console/issues
If you could also use a GUI console e.g.:
C:\> py -3 -m idlelib
Or http://ipython.org/notebook.html
There are many other IDEs for Python e.g.,
