如何获取非英文文件名的文件路径？

我制作了一个使用 MultipartRequest 上传文件的页面。我检查上传的文件没有问题。然后我在下载时遇到问题。

如果文件名是韩语，则程序无法读取文件的路径。我尝试在 server.xml 的 Connector 标记处设置“URIEncoding =“UTF-8”，但它不起作用。

如何获取名称为韩语的文件的路径？

当我下载名称为 KR 的文件时出现此问题： 404 not找到了

原文

I made a page for uploading files with MultipartRequest.
There is no problem when i check the uploaded files.
and then I have a problem when I'm downloading it.

If the file's name is in Korean, the program cannot read the path of the file. I tried to set "URIEncoding="UTF-8" at Connector tag at server.xml but it didn't work.

How can I get the path of the file which name is in Korean?
