arabic encoding in url

in my application users can attach files along with other fields..attached files are saved on a local folder..
no issues wen the file name is in english...problem is wit arabic file..say wen a user attaches شقشق.doc it gets saved in a local folder wit the same name..
now wen user wants to download this file from the local folder the url to this file path gets encoded as %d6%d4...and as such it cant find the required file..
How do i encode the url wit the correct arabic file name.

Use URLDecoder.decode to convert back into native encoding.
