I’m developing a typeface that is designed by a different person. In their design, their uppercase baseline is much lower than the lowercase baseline (and as much as possible they do not want major changes to the design).
Will I possibly encounter a problem in the future if I use the lowercase baseline for the metrics and just treat the uppercase baseline as an overshoot?
That is the way I would do it.
You can add another baseline with a filter for “case == Uppercase”:
This will look like this:
Thank you! Is it correct to assume that it would be okay for this specific uppercase baseline to have a negative value?
Am I right to assume those additional metrics don’t export and only live inside Glyphs? Curious if there are any consequences for the font alignment in apps/web.
Those extra metrics are not exported.
There are plans to export some of them in the future, e.g. in a BASE table.
Thanks, this is very helpful!
