I have only come across a few that used 8192, and as I said Gabriola uses 4096. One foundry that deserves to remain anonymous (but not for that reason) uses 4096 funits/em.Abraham Lee said:
I presumed that the main reason for increasing the funits/em would be to support delicate features, but I never would have imagined going to 4096 or 8192 funits/em. Are there many fonts that do this? Is the only reason _not_ to that it will increase file size because you're using larger integers? Does that have that much of an impact? Thanks for feeding my curiosity.
