我正在测试的数据如下 محمودعبدالعزيز
1 abc def 其中阿拉伯语为全名/名字，1为员工编号，abc为部门，def为电子邮件
解决方案
能否请您检查您列的排序规则是否也是UTF8 Unicode?
您可以运行mysql> show full columns from employees;
并检查输出以确保即使列的排序规则也能够接受UTF8.
编辑 除非设置了UTF-8字节顺序标记(BOM)，否则CSV无法存储UTF-8数据.
我不知道您保存的CSV是否保留UTF-8字符.也许您应该尝试在noteapd中打开CSV并查看是否正确获取了字符.
EDIT2 我刚刚修改了代码，以使其能够正确读取CSV，并且表单具有新的accept属性.

The data I am testing is as follows محمود عبدالعزيز
1 abc def Where arabic one is the full name/first_name, 1 is employee number, abc is department and def is email
解决方案
Could you please check if your column's collation is also UTF8 unicode?
You can run mysql> show full columns from employees;
and check the output to make sure even the column's collation is able to accept UTF8.
EDIT CSV can't store UTF-8 data unless the UTF-8 Byte Order Mark (BOM) is set.
I don't know if the CSV you are saving is retaining the UTF-8 characters. Maybe you should try opening the CSV in noteapd and see if you get the characters properly.
EDIT2 I just modified the code to have it read the CSV properly and the form has a new accept attribute.
