New submission from Eryk Sun <[email protected]>:
When reviewing issue 32904 I noticed that os.getcwdb still calls the CRT
_getcwd function. Apparently this was overlooked when implementing PEP 529. For
example:
>>> os.getcwd()
'C:\\Temp\\Lang\\αβγδ'
>>> os.getcwdb()
b'C:\\Temp\\Lang\\a\xdf?d'
Not only is the encoding wrong, but because the CRT uses GetFullPathNameA (the
CRT's implementation of _getcwd is convoluted, IMO), the call fails if the
current directory exceeds MAX_PATH. Python 3.6+ on Windows 10 otherwise
supports long paths.
