Thanks for that very helpful and detailed reply.

It all makes sense now.

I do have a Windows partition, so I’ll check out the options there.

It looks like RoboFont for Mac might be a good program for this task. Like FontLab, it’s also expensive, but RoboFont has a 15 day free trial and I can clean up all my affected fonts in that time.

With the cost of some of these fonts, you’d expect they would come with all this stuff sorted out in the first place. I can’t see the advantage of the way it is now with all the splintered families. Ah well, such is life.

Thanks again for your help!
