The Variation Selectors Supplement block spans U+E0100–U+E01EF, 240 codepoints in Plane 14 (Supplementary Special-purpose Plane). Every one of them is assigned in Unicode 16.0.
All of its characters belong to the Inherited script.
By general category: 240 non-spacing marks (Mn).
The first 240 arrived in Unicode 4.0 (2003).
Most characters here are combining marks. See combining diacritical marks.
Because it lies outside the BMP, every character here takes four bytes in UTF-8 and a surrogate pair in UTF-16.
