UnicodeDecodeError: 'gbk' codec can't decode byte 0x8b in position 214: illegal multibyte sequence

This error typically occurs when you try to decode a string that is not in the expected encoding format. In this case, the string contains a byte sequence that cannot be decoded using the 'gbk' codec.

To fix this error, you can try the following:

1. Check the encoding format of the string: Make sure that the string is in the expected encoding format. If not, you may need to convert the string to the correct format before decoding it.

2. Use a different codec: If the 'gbk' codec is not working, you can try using a different codec that supports the character set in the string.

3. Use a more robust decoding method: If you are unsure about the encoding format of the string, you can use a more robust decoding method that can handle multiple formats. For example, you can use the 'chardet' library to automatically detect the encoding of the string.

4. Check the source of the string: If the string is coming from an external source, such as a file or database, make sure that the source is using the correct encoding format.
