Hi there, I saw your comment from an announcement of the original Adobe Blank font from years ago. You mentioned:

It might be possible to create a minimal full-unicode font by using format 4 and 12 CMAP entries with full-range segments, both pointing to the non-spacing, non-marking glyph. This would probably give us a legal OpenType font that’s around 1kb. I’ll see if I can play around with that over the weekend. If I can, I’ll put it on github.

Did anything ever come of that? Is that this or one of the other repos here?

We invented a new CMAP subformat for that, so rather than using 4+12, you can now implement format 13 with a ConstantMapGroup that starts at 0x00000001 (because 0 is reserved) and ends at 0xFFFFFFFF and you're done.

The following does the format 13 trick:
