Module: Fontisan::Ufo::Convert::ToWoff2

Defined in:
lib/fontisan/ufo/convert/to_woff2.rb

Overview

UFO → WOFF2. Same two-step pipeline as ToWoff, but with the WOFF2 encoder (Brotli compression, optional glyf/loca transforms) instead of WOFF (zlib).

Returns the output_path; the WOFF2 binary itself lands at output_path.
