Eric V. Smith  added the comment:

I don't think there's a problem with Python here.

The complaint seems to be one or more of:
- The creating software allowed a newline to be in the filename.
- Windows allows the creation of filenames with newlines.
- The Windows UI doesn't handle filenames with newlines well.

In any event, Python can't do anything about these problems. I suggest we close 
this issue.

Because these special symbols are not handled under the Window, he will report 
an error and will not work properly

I'm not sure what you are asking here.

Looking at the screenshot I'd say that the zipfile you are trying to extract 
contains files with a newline in their name. That's a perfectly valid (although 
annoying) name on unix-y platforms.

The zipfile module does not have an API for rewriting the file name when 
extracting. It is far from clear to me that adding such a API would be 
generally useful.

Emulating this is fairly easy though, something like:

zf = zipfile.ZipFile(...)
for name in zf.namelist():
stream = zf.open(name)
data = stream.read()
stream.close()
with open(name.replace(...), "w") as stream:
stream.write(data)

New submission from Fcant :

When I Unzip a package using the zipfile module, the package’s filename has a 
newline character, which causes the Unzip to fail, so the UNZIP filename needs 
to be processed
