Hmmm i'm used to not thinking about this a lot as sw3d and unity both render the textures for you. So one way or the other a) on the fly, b) or during import or c) when building the project. Including isn't a problem either as you can distribute it encoded if you want.
For just rendering texts on textures i have never encountered problems. You only could get some if you build out meshes for extrusion afterwards or so. There you'll have to do some finetuning with code if you need it...
