UnicodeDecodeError: 'gb2312' codec can't decode byte 0xe7 in position 1635: illegal multibyte sequence

This error occurs when a string is being decoded using the 'gb2312' codec, but the byte sequence encountered is not a valid multibyte sequence in that encoding.

To fix this error, you can try the following:

1. Use a different codec to decode the string. For example, you can try using the 'utf-8' codec instead of 'gb2312'.

2. Check the encoding of the input data to ensure that it matches the expected encoding. If the input data is encoded in a different encoding than what is expected, you may need to convert it to the correct encoding before decoding it.

3. If the input data is not encoded in any standard encoding, you may need to use a custom codec or write your own decoding function to handle the special encoding.

Here is an example of how to decode a string using the 'utf-8' codec:

s = b'\xe7\x94\xb5\xe8\x84\x91' # bytes containing the encoded string
decoded_str = s.decode('utf-8') # decode using the 'utf-8' codec
print(decoded_str) # output: 电脑
