I’m using mkii. I’d like ot be able to copy-paste words form the resulting pdf. That works well, except for words that contain ligatures (e.g. fl fi etc.) Is there a way I can tell (Con)TeXt that the result must be copy-pastable.

To make matters slightly more complex I’m using Optima, converted on a Mac:
