GBK错误

2024-08-17 23:25:18   214人阅读

用CMD测试代码的时候，因为CMD默认用gbk支持print()，当UTF字符集出现超出GBK编码的字符是就会出现：

UnicodeEncodeError: ‘gbk’ codec can’t encode character u’\u200e’ in position 43: illegal multibyte sequence

可以在decode时，增加参数ignore对错误进行忽略。

 

bytes.decode(encoding="utf-8", errors="strict")bytearray.decode(encoding="utf-8", errors="strict")

Return a string decoded from the given bytes. Default encoding is ‘utf-8‘. errors may be given to set a different error handling scheme. The default for errors is ‘strict‘, meaning that encoding errors raise a UnicodeError. Other possible values are ‘ignore‘, ‘replace‘ and any other name registered via codecs.register_error(), see section Error Handlers. For a list of possible encodings, see section Standard Encodings.
