Crate system_fonts 

System font discovery and locale-based preset selection.

Detects the current system locale, maps it to a FontRegion, and resolves a prioritized list of installed fonts. On wasm, font discovery is not supported and the find_* functions return empty results.

use system_fonts::{find_for_system_locale, FontStyle};

let (_locale, region, fonts) = find_for_system_locale(FontStyle::Sans);
println!("region={region:?}, fonts={}", fonts.len());
