uucode is a Unicode library that is fully configurable at build time to only include the data for fields you need. It’s being used in Ghostty, libvaxis, flow and more. Now on zig 0.16.
const uucode = @import("uucode");
uucode.get(.simple_uppercase_mapping, 0x03C2) // ς -> Σ
uucode.get(.is_emoji, 0x1F34B) // true
