The Arabic Mathematical Alphabetic Symbols block spans U+1EE00–U+1EEFF, 256 codepoints in Plane 1 (Supplementary Multilingual Plane). 143 are assigned in Unicode 16.0; the other 113 are reserved for future characters.
All of its characters belong to the Arabic script.
By general category: 141 other letters (Lo), 2 math symbols (Sm).
The first 143 arrived in Unicode 6.1 (2012).
141 characters here have compatibility decompositions: they are formatting variants of other characters and are replaced by them under NFKC and NFKD. See normalization.
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.
