Bake Animation Nodes text animation Is it possible to bake an Animation Nodes animation that uses Trim Text and Text Object Output nodes?

I've been following this tutorial to create a typewriter text animation effect. 



I eventually want to remove the node tree but keep the animation and have seen that Animation Nodes has a Bake to Keyframes option.



However, when I press this nothing happens. If I remove the node tree the text remains static. Is there any way to bake this animation? I have also tried exporting the file to an Alembic file but the output is only a few hundred bytes in size and doesn't work.
