New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

When open a ZIP archive, write a file with non-ascii name in it, and, not closing the archive, read that file back, it fails:

>>> import zipfile
>>> with zipfile.ZipFile('test.zip', 'w') as zf:
...     zf.writestr('йцукен', '')
...     zf.read('йцукен')
Traceback (most recent call last):
  File "<stdin>", line 3, in <module>
  File "/usr/lib/python3.8/zipfile.py", line 1440, in read
    with self.open(name, "r", pwd) as fp:
  File "/usr/lib/python3.8/zipfile.py", line 1521, in open
    raise BadZipFile(
zipfile.BadZipFile: File name in directory 'йцукен' and header b'\xd0\xb9\xd1\x86\xd1\x83\xd0\xba\xd0\xb5\xd0\xbd' differ.
