It doesn't happen often that I need this LISP, but when I have, it has been a life saver.
In today's situation, we are linking a CAD file into a Revit project and the text would not come through. Looking at the CAD file we received, the text is all attributes that have been exploded.
This little gem saved the day. One other thing we end up doing is changing the font for the text in AutoCAD to Zurich LT BT. It looks like Simplex, but plots way better out of Revit.
I don't remember where this lisp came from and it isn't documented, but thank you so much stranger.
