Ok, so I found part of the answer to my question, but my specific case is it doesn't work for my Mac users.
I have a Mac user who gets sent a weekly report. He's in Russia and when individuals fill out our forms in Russian, it appears corretly in Marketo, it syncs with SFDC correctly, and when I download it to my PC manually, using Excel 2007, it appears correctly.
When we download the file as Excel 2007 to a Mac, it shows up as wingdings script.
Any suggestions on how to corret this. Is this a Mac issue where settings within the Mac need to be addressed?
