utf-8 codec can't decode byte 0xba in position 115: invalid start byte

This error usually occurs when there is an issue with decoding a byte sequence using the UTF-8 codec. The byte 0xba indicates that there might be a non-UTF-8 character in the input string.

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

1. Check the encoding of the input source: Ensure that the source of the input data is encoded using UTF-8. If it's encoded using a different encoding, you will need to decode it using the appropriate codec before processing it.

2. Handle encoding errors: If you expect non-UTF-8 characters in the input string, you can handle the decoding error by specifying the `errors` parameter when decoding the byte sequence. Common error handling options include `'ignore'`, `'replace'`, or `'backslashreplace'`.

Here's an example of how you can handle the error and decode the byte sequence:

byte_sequence = b'\xba'
try:
    decoded_string = byte_sequence.decode('utf-8')
    print(decoded_string)
except UnicodeDecodeError as e:
    print(f"Error decoding byte sequence: {e}")

Remember to replace `byte_sequence` with your actual byte sequence.

By handling the error or ensuring proper encoding, you should be able to resolve the `utf-8 codec can't decode byte` issue.
