The Newa block spans U+11400–U+1147F, 128 codepoints in Plane 1 (Supplementary Multilingual Plane). 97 are assigned in Unicode 16.0; the other 31 are reserved for future characters.
All of its characters belong to the Newa script.
By general category: 60 other letters (Lo), 13 non-spacing marks (Mn), 10 decimal digits (Nd), 8 other punctuation (Po), 6 spacing marks (Mc).
The first 92 arrived in Unicode 9.0 (2016); later additions came in 11.0 (1), 12.0 (1), 13.0 (3).
Because it lies outside the BMP, every character here takes four bytes in UTF-8 and a surrogate pair in UTF-16.
