I am stuck since few days in converting of a xml to csv but i see it going nowhere. I've tried this script with and without special characters and its working perfectly when there is no special special character. Special character, iam refering to german characters ü,ß and all those.

import xml.etree.ElementTree as ET
import csv


tree = ET.parse("demoxml.xml")
root = tree.getroot()

f = open('demoxml.csv', 'w', newline='')

csvwriter = csv.writer(f)

count = 0

head = ['Author','Title','Genre','Price','Publish date', 'description']

csvwriter.writerow(head)

for time in root.findall('book'):
    row = []
    Author = time.find('author').text
    row.append(Author)
    Title = time.find('title').text
    row.append(Title)
    Genre = time.find('genre').text
    row.append(Genre)
    Price = time.find('price').text
    row.append(Price)
    Publish = time.find('publish_date').text
    row.append(Publish)
    Description = time.find('description').text
    row.append(Description)
    csvwriter.writerow(row)
f.close()

demo.xml

Where should i put this decode() or encode('utf-8'), i tried it almost at every step but still failed.
