I'm guessing that when PEP 277 refers to the posix module maybe it means
the os module. What happens if you pass a Unicode string to listdir(),
e.g. os.listdir(u'.')?
Hmm, looks promising:
In [3]: os.listdir(u'.')
Out[3]: [u'enterData.py', u'test.py', u'SPY2.csv', u'\xe1\xe9\xed\xf3\xfa']
In [4]: p=_[3]
In [5]: p
Out[5]: u'\xe1\xe9\xed\xf3\xfa'
In [6]: os.rename(p, u'foo')
In [7]: os.listdir(u'.')
Out[7]: [u'enterData.py', u'test.py', u'SPY2.csv', u'foo']
