Are We Legacy Computing Yet? (arewelegacycomputingyet.com)

The article surveys Unicode’s “Symbols for Legacy Computing” character blocks (U+1FB00–U+1FBFF and U+1CC00–U+1CEBF) and tests which terminal emulators can render them correctly. It explains that many terminals rely on custom drawing logic rather than standard font glyphs, and that this affects how well the symbols connect and display as a coherent UI or graphic. Using a script that forces missing-glyph fonts, the author reports strong support in ghostty and vte-based terminals (with xtermjs supporting much of the main block but none of the supplement, and urxvt supporting essentially nothing).
