New submission from Mike Auty <mike.a...@gmail.com>:

I've found open to have difficulty with a resolved pathlib path:

Example code of:

   import pathlib
   path = "Z:\\test.py"
   with open(path) as fp:
       print("Stock open: works")
       data = fp.read()
   with open(pathlib.Path(path).resolve().as_uri()) as fp:
       print("Pathlib resolve open")
       data = fp.read()

Results in:

Z:\> python test.py
Stock open: works
Traceback (most recent call last):
  File "Z:\test.py", line 12, in <module>
    with open(pathlib.Path(path).resolve().as_uri()) as fp:
FileNotFoundError: [Errno 2] No such file or directory: 
"file://machine/share/test.py"

Interestingly, I've found that open("file:////machine/share/test.py") succeeds, 
but this isn't what pathlib's resolve() produces.  It appears as though 
file_open only supports hosts that are local, but will open UNC paths on 
windows with the additional slashes.  This is quite confusing behaviour and 
it's not clear why file://host/share/file won't work, but 
file:////host/share/file does.

I imagine this is a long time issue and a decision has already been reached on 
why file_open doesn't support such URIs, but I couldn't find the answer 
anywhere, just issue 32442 which was resolved without clarifying the 
situation...
