As I said, I have no idea how they got there in the first place....!

something, somewhere, converted those (and only those, 
apparently) potential ligatures. I'm very curious as to how it 
happened and will explore whether it's something to do with 
Dictate (and report it to them).

thanks again. I learned something, at least...
