Ah, PP, you have discovered what I learned a while ago. When importing stuff into Word etc, run it through a vanilla text editor to remove all the nonsense.
I use a prehistoric one called PFE (Programmers' File Editor) - probably 15 years old, but does the job superbly. Then Word doesn't go silly.
The same technique will also allow editing of stuff to make .csv files that can be imported and processed.
