UnicodeDecodeError: 'gbk' codec can't decode byte 0xae in position 206: illegal multibyte sequence

This error is typically seen when trying to decode a string of characters that is not compatible with the GBK encoding. GBK is a character encoding used for simplified Chinese characters in China, and it is possible that the string being decoded contains characters not found in GBK.

To resolve this error, you can try:

1. Changing the encoding to a different one that supports the characters in the string.
2. Removing the problematic characters from the string.
3. Using a different library or tool that can handle the encoding.

For example, you could try decoding the string with UTF-8 instead of GBK:

string = b'\xae'
decoded_string = string.decode('utf-8')

Alternatively, you could remove the problematic byte from the string:

string = b'hello \xae world'
string = string.replace(b'\xae', b'')
decoded_string = string.decode('gbk')

If neither of these solutions work, you may need to investigate the source of the string and why it contains characters that are not compatible with GBK.
