magically fix (most of) this zip with corrupted filenames I got

zipmagic.py

import codecs
import os
import shutil
import zipfile

def magic(fname):
    if type(fname) == unicode: return fname
    assert type(fname) == str
    return codecs.decode(fname, 'shift-jis', 'replace')

with zipfile.ZipFile('Chinese.zip') as zipf:
    for info in zipf.infolist():
        # check if it's a directory
        # os.path.split splits it into (_, last pathname component)
        if not os.path.split(info.filename)[1]: continue

        magicname = magic(info.filename)
        print magicname

        outfname = os.path.join('out', magicname)
        # https://stackoverflow.com/questions/12517451/python-automatically-creating-directories-with-file-output
        if not os.path.exists(os.path.dirname(outfname)):
            os.makedirs(os.path.dirname(outfname))

        with zipf.open(info) as inf:
            with open(outfname, 'w') as outf:
                shutil.copyfileobj(inf, outf)
