I rarely outsource my type design research but I'm hitting a wall and would love to know if I'm the only with this particular problem:
When it comes to creating a locl feature for the Dutch language to substitute /i/j with the digraph /ij, how do you handle exceptions to the rule, e.g. loan words like bijou, Fiji, or even the Dutch word bijectie etc? Do you turn a blind eye to this and let the user figure out how to disable the substitution? Do you make exceptions for the most common words? Did anyone come up with a rule that would take care of all exceptions neatly and efficiently without weighing down my font files?
Thanks in advance for your help!
