Hi, there's this rather new mechanism for preventing ligatures: \startexceptions[de] au{f-}{f}{ff}(f\zwnj f)asse au{f-}{f}{ff}(f\zwnj f)asste \stopexceptions Two questions: 1. Can you have multiple \startexceptions[de] environments ? Will they accumulate ? (I'm thinking about preparing a general list of exceptions, but of course you will also want individual exceptions...) 2. What is the exact meaning of these four arguments ? {1}{2}{3} is clear, but what about the parentheses ? Best, Denis
