UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 17: invalid continuation byte

This error occurs when Python tries to decode a byte sequence into a string using the UTF-8 codec, but encounters a byte that cannot be decoded. In this case, the byte at position 17 has the value 0xcf, which is not a valid continuation byte in UTF-8 encoding.
To fix this error, you can try the following:
1. Check that the input data is actually encoded in UTF-8. If it is not, you may need to use a different codec to decode it.
2. If the input data is supposed to be in UTF-8, then the issue may be with the byte sequence itself. Try removing or replacing the problematic byte(s) and see if that resolves the issue.
3. If you are working with files, make sure you are opening them in binary mode (i.e. with the 'b' flag), as text mode may cause encoding issues.
4. You can also try using the 'errors' parameter when decoding, which will tell Python how to handle errors during decoding. For example, you can use 'ignore' to skip invalid bytes, or 'replace' to replace them with a special character.
Example:
```python
data = b'some byte string with \xcf invalid byte'
try:
decoded_data = data.decode('utf-8', errors='ignore')
except UnicodeDecodeError as e:
print(f"Error: {e}")
else:
print(decoded_data)
```
Output:
```
some byte string with invalid byte
```
