Downloading attachments is garbled

Question

I am trying to download an attachment from Microsoft Exchange OWA webpage and it used to convert the name of the .ZIP from the Subject line (e.g. subjectname.zip). However, since FF29, Japanese characters in the subject will show up garbled in the filename (e.g. when you have "ト" in the Subject, the filename returns as %e3%83%88.zip, instead of ト.zip). IE and Chrome work fine.
