A supplemental block ([[Symbols for Legacy Computing Supplement]]) was added with Unicode 16.0.
A supplement block was approved in 2022 for inclusion in Unicode 16.0, following proposal L2/21-235.<ref>{{Cite web|url=https://www.unicode.org/alloc/Pipeline.html|title=Proposed New Characters: The Pipeline|website=www.unicode.org}}</ref> The Supplement block includes characters from Amstrad, Apple 8-bit, Kaypro CP/M, Ohio Scientific, Robotron KC, Sharp MZ computers, HP terminals, and TRS-80. It includes a larger set of semigraphics in the form of 230 "octant" characters, large images split into four "characters", and the "large type" characters used for building large text characters.<ref>{{cite web |title=Proposal to add further characters from legacy computers and teletext to the UCS |url=https://www.unicode.org/L2/L2021/21235-terminals-supplement.pdf |date=2021-12-20}}</ref>
