当我打开

成员--.csv文件时提取成员后，我看到UniCode字符出现问题。

如何解决此问题？

我正在使用excel 2016

问题不在于你的代码，而是excel。当Excel打开一个文件时，它使用的编码是Windows版本的默认编码，而这种编码从来不是UTF-8——它是Unicode出现之前他们发明的许多代码页之一

如果使用文本导入向导，则可以选择文本编码，如果需要，可以在其中选择UTF-8。但每次你需要打开CSV时，这都是一种痛苦

有一种方法可以让Excel识别文件是UTF-8编码的，并自动使用它，许多Microsoft产品使用相同的技巧。如果文件以UTF-8编码的Unicode（3字节序列0xEF、0xBB、0xBF）开头，Excel将识别该文件是UTF-8编码的，并覆盖其默认值。如果使用特殊编码

'utf_8_sig'

，Python将自动使用此BOM序列启动文件

with open("members-" + re.sub("-+","-",re.sub("[^a-zA-Z]","-",str.lower(target_group.title))) + ".csv","w",encoding='utf_8_sig') as f:

---

不建议您在每个文件的开头都添加此特殊签名，除非您知道需要它的应用程序会使用它。

这太多代码了，我相信您可以用更少的代码演示此问题。我是c#开发人员，不熟悉python。那剧本写得很好。但unicode字符不能显示在csv文件上。在该代码上搜索utf-8以查看要检查的代码。代码中似乎没有问题。但是excel显示unicode字符（阿拉伯语）有什么错呢？请尝试使用而不是

“UTF-8”

。
