Should I delete all my empty glyphs?

Post by Psymon » Fri Jan 04, 2019 9:54 pm

When you've finished up your font, and are ready to "put it out there" for people to download/use, how important is it to delete all the unused, empty glyphs? In each of my fonts I have tons and tons of empty glyphs in the PUA section of each font. The reason for that is because all the various ligatures in each font are coordinated in the same slots, but each font has different ligs, and some not many ligs at all. It's nice to leave all those empty slots there while I'm working on this family (so that if I discover I need to add in an additional lig I can squeeze it in easily), but is it "important" to delete them when you're finished up? I can see that it would bring the file size down a little, but they're all just empty slots, so I can't imagine that it would be a huge saving in file size, really.

Other than that, though, is there any real practical reason to delete all the empty slots (other than the necessary ones, of course)?

It is best to delete all unused glyphs. Otherwise external software like word processors or font managers might show the glyphs to the end user while you never intended this.

And, yes, it will also save some bytes.

We could add a new feature which allows you to mark a glyph to be included on export. This is similar to what we're used with our manual generation software.
