HttpResponseRedirect to a file causes UnicodeEncodeError

[Alexander]

I'm trying to download via GET a file with name in russian and getting

Environment:

Request Method: GET
Request URL: http://172.16.23.33/file/4719e0bdedaa4f741f032991894d52ecb08c3476a598504fd1fee92d

The code which cause this error:

upfile = UpFile.objects.get(file_hash=file_hash)
path = os.path.join(settings.UPLOAD_ROOT, request.user.username,
upfile.file_name)
return HttpResponseRedirect(path)

If filename in English everything works ok.
The file was uploaded this way:

dir_path = os.path.join(settings.UPLOAD_ROOT, request.user.username)
upfile = UpFile.objects.create(user=user, file_name=file.name,
file_hash=file_hash,
file_content_type=file.content_type,file_path=file_path,
file_url=file_url, file_size=file.size)
path = '%s/%s' % (dir_path, file.name)
destination = open(path.encode('utf8'), 'wb+')
for chunk in file.chunks():
    destination.write(chunk)
destination.close() 

DEFAULT_CHARSET = 'utf-8'
DATABASE_ENGINE = 'sqlite3' 

The name of the file is correctly readable in my system(ls -lh):
locale

Fixed formatting -- please use preview.

The description for #11522 seems to say the fix proposed there would also fix this case, so I'm going to close this as a dup of that one.
