If prefer_stream is True (default), asks for stdin.encoding first, to match the calling Terminal, but that is often None for subprocesses. Then fall back on locale.getpreferredencoding(), which should be a sensible platform default (that respects LANG environment), and finally to sys.getdefaultencoding() which is the most conservative option, and usually ASCII on Python 2 or UTF8 on Python 3. tasciitcp0sˆInvalid code page cp0 detected - using cp1252 instead.If cp1252 is incorrect please ensure a valid code page is defined for the process.tcp1252N( tNoneRtsyststdintlocaletgetpreferredencodingt ExceptiontgetdefaultencodingtwarningstwarntRuntimeWarning(t prefer_streamtenc((sQ/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/ipython_genutils/encoding.pyR&s   ( t__doc__R R RRRtTrueRtDEFAULT_ENCODING(((sQ/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/ipython_genutils/encoding.pyts      !
