Without more specific info, nobody can tell you much. These are Unicode and font errors, but you haven't even mentioned the exact version of AE, much less anything about your OS X or the exact computer.
Hey, sorry I wasn't aware of the error so I didn't know it was a specific error. I am running a Macbook Pro, early 2015, 2.7GHz i5, 8 GB RAM, intel iris Graphics 6100, OSX El Capitan 10.11.6, After Effects 2015.3
Thank you for your response!
Did you ever get his solved?
Yes I did, in my situation it was a corrupt file I was using.
