This is a very early release of a cross-platform font enumeration/fallback library. Right now, it supports querying fonts from a pre-baked static collection (Windows and macOS only for now) and from registered fonts scanned from user provided buffers.
More platforms and features to follow.
The only interesting thing to do with this library at the moment is to run the itemize
example with some text to confirm that the runs and reported fonts look reasonable. It will
report selected font family names for each run and nominal glyph identifiers for each character.
cargo run --example=itemize "العربية نص جميل. ܠܸܫܵܢܵܐ ܕܠܐ द क्विक ब्राउन फ़ॉक्स jumps over the lazy 🦸🏾♀️. Ꭰꮿꮩꮈ 1 Ꮒꭶꮣ, ߓߊߘߋ߲ ߕߐ߬ߡߊ ߟߎ߬"
