Last Call for Review of Proposed Corrections: WOFF File Format 2.0 Recommendation

The Web Fonts Working Group has proposed corrections to the W3C Recommendation of WOFF File Format 2.0. Based on experience with WOFF 1.0, which is widely deployed, this specification was developed to provide improved compression and thus lower use of network bandwidth, while still allowing fast decompression even on mobile devices. This is achieved by combining a content-aware preprocessing step and improved entropy coding, compared to the Flate compression used in WOFF 1.0. Comments, including implementation experience, are welcome via GitHub through 10 May 2022.
