UnicodeDecodeError: 'gbk' codec can't decode byte 0x9d in position 4771: illegal multibyte sequence

On my Windows10, the default decode mode is **gbk**.
In this file `cwe2\database\699.csv` line 418 col 3402, **gbk** can't decode the `0xE2 0x80 0x9C`.

Suggestion:
When open *.csv files, should explicitly use `encoding='utf-8'`.

Thank you very much for your project!
