But why should it make glob() fail? This sounds like an implementation
detail of glob. Here's some pseudo-code::
string = False
if isinstance(pattern, str):
string = True
if platform == 'POSIX':
pattern = bytes(pattern, encoding=defaultencoding)
rawfiles = os.listdir(os.path.dirname(pattern) or pattern)
if string and platform == 'POSIX':
return [str(f) for f in rawfiles if match(f, pattern)]
This way the traceback occurs if anything in the result set is
undecodable. What am I missing?
