Keynote symbols not exporting to PDF

How do I make Keynote export % symbols to a PDF? For some reason it is not exporting. I tried using multiple fonts. I was pretty surprised to see that Keynote was leaving characters off of exports. Usually Apple is pretty good about accuracy.

Yosemite OS 10.10.2

Keynote 6.5.2 (2119)

Macbook Pro 15 Retina

Fonts tried: Helvetica, Futura Std

Could not export % symbols adjacent to numbers
