The Ancient Greek Numbers block spans U+10140–U+1018F, 80 codepoints in Plane 1 (Supplementary Multilingual Plane). 79 are assigned in Unicode 16.0; the other 1 are reserved for future characters.

All of its characters belong to the Greek script.

By general category: 53 letter numbers (Nl), 20 other symbols (So), 6 other numbers (No).

The first 75 arrived in Unicode 4.1 (2005); later additions came in 7.0 (2), 9.0 (2).

Because it lies outside the BMP, every character here takes four bytes in UTF-8 and a surrogate pair in UTF-16.
