It probably could be if you represented the data with fairly large blocks, but I don't see the point either way. Sure they could have more directly encoded ASCII into texture data, but why bother when they already have a system in place for rendering ASCII to a texture as text? It'd be overkill if they were building this feature from the ground up starting with nothing but a string, but they weren't.
