Problem
After mounting a usb storage medium, I try to copy a file to it, but I get the following error:
$ cp 黃.txt /media/usb/
cp: cannot create regular file '/media/usb/黃.txt': Invalid argument
The problem occurs only with files which include Chinese (CJK) encoded characters.
The following works without problem:
$ cp test.txt /media/usb/
Solution
Check the options the usb medium has been mounted:
$ grep /media/usb/ /proc/mounts
