[issue10757] zipfile.write, arcname should be bytestring

[Jacek Jabłoński]

New submission from Jacek Jabłoński <conexion2000 at gmail.com>:

file = 'somefile.dat'
filename = "ółśąśółąś.dat"
zip = zipfile.ZipFile('archive.zip', 'w', zipfile.ZIP_DEFLATED)
zip.write(file, filename)

above produces very nasty filename in zip archive.
*************************************************************
file = 'somefile.dat'
filename = "ółśąśółąś.dat"
zip = zipfile.ZipFile('archive.zip', 'w', zipfile.ZIP_DEFLATED)
zip.write(file, filename.encode('cp852'))

this produces TypeError: expected an object with the buffer interface

Documentation says that:
There is no official file name encoding for ZIP files. If you have unicode file names, you must convert them to byte strings in your desired encoding before passing them to write().

I convert them to byte string but it ends with an error.
If it is documentation bug, what is the proper way to have filenames like "ółśąśółąś" in zip archive?
