Unicode Block - Symbols for Legacy Computing Supplement
Symbols for Legacy Computing Supplement is a collection of graphic characters that preserves the visual output of early computers, terminals, and home systems from the 1970s and 1980s, including custom glyphs from platforms like the Commodore 64, Apple II, and various text-mode terminals. It extends the earlier Symbols for Legacy Computing block by adding more specialized icons, block elements, shading patterns, and line-drawing characters, as well as symbols for teletext, videotex, and printer control. This supplement helps archivists, emulator developers, and researchers accurately reproduce historical software and digital artifacts without relying on proprietary fonts or lossy approximations. By encoding these legacy symbols as standard text characters, it ensures that vintage computing output remains interoperable, searchable, and displayable on modern systems while preserving the distinctive visual identity of those early machines.
