01
Assigned versus possible
Unicode reserves 1,114,112 code points in total. Only a fraction are assigned to actual characters — a little under 160,000 in the current version — and the rest are unassigned, reserved or set aside for private use.
Each release adds a few thousand more, mostly for historic scripts and specialist notation rather than emoji.
- 1,114,112 code points possible
- Just under 160,000 assigned today
- Around 3,800 of those are emoji
02
Why the number keeps moving
New scripts, new notation and new emoji arrive with each version. Characters are never removed, because that would break existing text, so the total only ever grows.
