The Latin Extended-B block spans U+0180–U+024F, 208 codepoints in Plane 0 (Basic Multilingual Plane). Every one of them is assigned in Unicode 16.0.

All of its characters belong to the Latin script.

By general category: 103 uppercase letters (Lu), 96 lowercase letters (Ll), 5 other letters (Lo), 4 titlecase letters (Lt).

The first 148 arrived in Unicode 1.1 (1993); later additions came in 3.0 (30), 3.2 (1), 4.0 (4), 4.1 (11), 5.0 (14).

91 characters here are precomposed and have canonical decompositions, so NFD splits them into a base letter plus combining marks. See normalization.
