The Old Hungarian block spans U+10C80U+10CFF, 128 codepoints in Plane 1 (Supplementary Multilingual Plane). 108 are assigned in Unicode 16.0; the other 20 are reserved for future characters.

All of its characters belong to the Old Hungarian script.

By general category: 51 uppercase letters (Lu), 51 lowercase letters (Ll), 6 other numbers (No).

The first 108 arrived in Unicode 8.0 (2015).

Most letters here are written right to left. See bidirectional text.

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