UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd0 in position 0: invalid continuation byte

This error message indicates that there is a problem with decoding a byte sequence using the UTF-8 codec. The byte sequence contains a byte that is not a valid continuation byte in UTF-8 encoding.

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

1. Identify the source of the byte sequence that is causing the error. This could be a file, a network stream, or a string that was encoded using a different encoding.

2. If the source is a file, make sure that the file is encoded using UTF-8. You can use a text editor or a command-line tool to check the encoding of the file.

3. If the source is a network stream or a string, check the encoding used to encode the data. It is possible that the data was encoded using a different encoding than UTF-8.

4. Once you have identified the encoding of the data, you can use the appropriate codec to decode the data. For example, if the data was encoded using ISO-8859-1, you can use the following code to decode it:

data = b'\xd0\xbf\xd1\x80\xd0\xb8\xd0\xb2\xd0\xb5\xd1\x82'
decoded_data = data.decode('iso-8859-1')

5. Once you have decoded the data, you can then encode it using UTF-8 if needed:

encoded_data = decoded_data.encode('utf-8')

6. If you are still having issues, you may need to consult the documentation or seek help from other developers who have experience with the specific data source or encoding.
