WOFF2 is pretty cool. I recently ported the C++ woff2 library (https://github.com/google/woff2 - as used by Chrome, Firefox) to Rust (https://github.com/nicoburns/wuff), and it turn out WOFF2 has a bunch of custom font-specific compression algorithms.

WOFF1 is kinda boring from a technical perspective: it's just gzip in a font container.
