Useful indeed.

 Note 2: os.listdir(u"path") returns Unicode strings for names that can
 be decoded with sys.getfilesystemencoding() but silently returns byte
 strings for names that can't be decoded. That is, the return value of
 os.listdir(u"path") is potentially a mixed list of Unicode and byte
 strings.


Is the following non-ascii enough?

 $ ls | cat
 Hallå_där
 Köp_blåbär

With unicode:
 [u'Hall\xe5_d\xe4r', u'K\xf6p_bl\xe5b\xe4r']

Without:
 ['Hall\xc3\xa5_d\xc3\xa4r', 'K\xc3\xb6p_bl\xc3\xa5b\xc3\xa4r']
