UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 28: invalid continuation byte

This error typically occurs when you try to decode a byte sequence using the 'utf-8' codec, but the byte sequence contains invalid or unexpected characters. In this case, the error specifically mentions that it encountered an invalid continuation byte at position 28.

To resolve this error, you can try the following steps:

1. Specify a different encoding: If you know the correct encoding of the byte sequence, you can try specifying that encoding instead of 'utf-8'. For example, if the byte sequence is encoded using 'latin-1', you can use `decode('latin-1')` instead of `decode('utf-8')`.

2. Handle errors during decoding: If the byte sequence contains invalid characters, you can instruct Python to ignore or replace those characters during decoding. For example, you can use `decode('utf-8', errors='ignore')` to ignore invalid characters or `decode('utf-8', errors='replace')` to replace them with the Unicode replacement character.

Here's an example of handling the error and ignoring invalid characters:

byte_sequence = b'some_byte_sequence'
decoded_text = byte_sequence.decode('utf-8', errors='ignore')
print(decoded_text)

Remember to adjust the encoding and error handling based on your specific situation.
