🔍 What went wrong?

I upload a file using the file selector, if the file name contains non-ascii characters (for example, chinese characters), then all the non-ascii characters are removed from the file name. But I still want to get the original file name.

steps to reproduce the bug:

1. create a file selector
2. upload a file named "abc_变量分析_jf_356.xlsx"
3. get the file name from the "content" property, the file is renamed to "abc__jf_356.xlsx", all the non-ascii letters are removed.

How can I get the original file name?

✅ Expected Behavior

upload a file named "abc_变量分析_jf_356.xlsx", and I get the file "abc_变量分析_jf_356.xlsx" keeping all the non-ascii characters.
