Python : BadZipFile: File name in directory and header differ

I am using this method to extract this zipfile.

r = requests.get(url)
z = zipfile.ZipFile(io.BytesIO(r.content))
z.extractall("Documents_zip")    #This is where the error occurs

And I get this error from Python :

BadZipFile: File name in directory '2017-08-29_Cerfa_CpC_Ombi+¿res_Lac_Th+⌐sauque.pdf' and header b'2017-08-29_Cerfa_CpC_Ombi\xc3\xa8res_Lac_Th\xc3\xa9sauque.pdf' differ.

I do not know much about the zipfile module but I found that it is too strict and that it is not necessary to check file name and header.

How can I extract without raising the error ?

EDIT 1 :

I created this function to avoid the error to raise. It just returns a boolean to indicate if whether or not, the zip extraction was run.

def download_zip(z, path):
    if not(z.testzip()):
        z.extractall(path)
        return True
    else:
        return False

I finalised the previous function. It extract the files of a zip into a folder namde path. If there is a problem, the named of the current directory is changed and the number of corrupted files is indicated. The function also returns this number.

import os
import zipfile
def download_zip(z, path):
    names_files = z.namelist()
    count = 0
    for my_file in names_files:
        if my_file:
            if z.testzip():
                if not(my_file in z.testzip()):
                    try:
                        z.extract(my_file, path=path)
                    except zipfile.BadZipfile:
                        count = count +1
            else:
                z.extract(my_file, path=path)
        else:
            count = count + 1

    if count != 0:
        my_path = os.getcwd()
        parent = os.path.dirname(my_path)
        os.chdir(parent)
        os.rename(my_path, my_path + ' - ' + str(count) + ' doc du zip non extrait')
        os.chdir(my_path + ' - ' + str(count) + ' doc du zip non extrait')
    return count
