Process mixed bytes data into python list

Question

I am reading data remote .dat files for EDI data processing.

Original Data is some string bytes:

b'MDA1MDtWMjAxOS44LjAuMDtWMjAxOS44LjAuMDsyMDIwMD.........'

Used decode as below...

byte_data = base64.b64decode(byte_data)

Gave me this below byte data. Is there a better way to process below bytes data into python list ?

b"0050;V2019.8.0.0;V2019.8.0.0;20200407;184821\r\n0070;;7;0;7\r\n0080;11;50;bot.pdf;Driss;C:\\Dat\\Abl\\\r\n0090;1;Z;Zub\xf6r;0;0;0;Zub\xf6r;;;Zub\xf6r\r\n

Tried decode with uft-8, didn't work.

byte_data.decode('utf-8')

Tired to convert to string and read as CSV but did not help, landed on original data. Need to keep some of the string as it is and convert \xf6r \r \n

data = io.StringIO(above_data)
data.seek(0)
csv_reader = csv.reader(data, delimiter=";")

Answer 1

It didn't work with 'utf-8' because it's not 'utf-8', it's probably 'ISO-8859-1' (latin-1)

text = byte_data.decode('ISO-8859-1')

because \xf6 is ö in 'ISO-8859-1'

Answer 2

Is it definitely utf-8 encoded?

This might help guide to what decoder to use:

import chardet
print(cardet.detect(byte_data))
