UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe8 in position 4: invalid continuation byte

This error occurs when Python tries to decode a string using the UTF-8 codec, but encounters a byte that is not a valid continuation byte. The byte 0xe8 is the first byte of a multi-byte character in the ISO-8859-1 encoding, but it is not a valid continuation byte in UTF-8.

To fix this error, you need to determine the encoding of the input data and use the correct codec to decode it. You can try using other codecs such as ISO-8859-1 or Latin-1, or you can use the chardet library to automatically detect the encoding.

For example, if you have a file with ISO-8859-1 encoding, you can read it using the following code:

with open('file.txt', encoding='iso-8859-1') as f:
    data = f.read()

Alternatively, you can use chardet to detect the encoding automatically:

import chardet

with open('file.txt', 'rb') as f:
    raw_data = f.read()
    encoding = chardet.detect(raw_data)['encoding']

with open('file.txt', encoding=encoding) as f:
    data = f.read()
