This script is for Mac users!
I use Microsoft Outlook on Macbook Pro at work.
And I get many Korean filename attachments through email
and most of them turn into unrecognizable url encoded characters like "ABC%D0%EB%CF.pptx".
So I made this python script for Hazel to automatically recognizes "%" included file then fix the file name.
this is tested on python 2.7.10.
