导出为CSV时,俄语字符将不会显示

Question

我有这个代码,我用它来导出一个CSV查询,问题是,如果我用Excel打开这个俄语字符将不会显示,但如果我打开它与数字(Mac)他们显示.

现在,我无法解决这个问题.我添加了一些我在互联网上看到的线条而没有...

该脚本不是为UTF-8编码数据创建的.它几乎按原样转储数据.生成的CSV文件将包含(可能)有效的UTF-8编码数据,但不包含签名.在没有签名的情况下,某些软件会使用启发式方法来检测编码; 其他人,比如Excel,不会.

您必须告诉excel将文件视为UTF-8编码.为此,您需要在Excel中导入文件(数据>获取外部数据>从文本)而不是直接打开它(双击或使用文件>打开).在文本导入向导中,选择适当的编码,Excel应正确导入数据.请参阅下面的截图.

或者,您可以尝试手动添加UTF-8签名.我自己没试过.
