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

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)

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

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.
