Writing to a json file with Polish characters - python-3.x

Question

I am using a JSON file to send data from an LDAP database on linux ADDC SAMBA for further processing. I fetch the data with a script written in python3. My problem is that some fields contain Polish characters that are encoded in unicode, for example "Bo\u017Cena \u017Ar\u00F3dlana" should be "Bożena Źródlana" . I would like the file to contain already decoded data so that I can read them without guessing what character is behind the unicode code.
I need to ask for help where in my code I should put something similar to a decoder so that the entire file is already saved as decoded and containing Polish special characters
my python3 code:

Use the following to suppress Unicode escape codes and write the data UTF-8-encoded to support non-ASCII characters.
with open(json_cmptrs_data, 'w', encoding='utf8') as jsonfile:
json.dump(data, jsonfile, ensure_ascii=False)
Working example:
import json
data = {"cn": ["Bo\u017Cena \u017Ar\u00F3dlana"]}
with open('output.json', 'w', encoding='utf8') as file:
json.dump(data, file, ensure_ascii=False)
output.csv (UTF-8-encoded):
{"cn": ["Bożena źródlana"]}
