• Introducing Glyph Protocol for Terminals

  • My Notes

    • Person/Raphael Amorim proposes Glyph Protocol as a terminal protocol for applications to register custom vector glyphs at runtime and query whether a codepoint is renderable.
    • The post frames missing glyphs as a distribution problem: users install large patched fonts so a TUI can render a few icons, while application authors still cannot know whether the glyphs are actually present.
    • The protocol uses APC framing with verbs for support, query, register, and clear; registrations are restricted to Unicode Private Use Area codepoints so programs cannot spoof normal text.
    • The first payload is a constrained TrueType glyf outline: small, vector, already understood by terminal text renderers, and rendered in the current foreground color.
    • The comparison to Kitty Image Protocol and DECDLD makes the design feel like a precise terminal-native layer: not an image protocol, not a bitmap character-set relic, but glyph registration with modern safety boundaries.
