Great app!... Has some bugs.... Please fix!

The app works great, although you need an Internet connection to convert files. I have noticed that certain characters do not convert properly though. I am using this app to convert my calculus homework into PDF to annotate but it does not convert the "prime" notation symbol for some reason. (It looks kinda like a single quote at an angle. This can be a big problem, for those of you who have never taken calculus!).

Has anyone else noticed certain characters not showing up?

Will this be fixed in an update?
