Yesterday, two changes were submitted to the Font Compression Reference project: https://code.google.com/p/font-compression-reference/ The first change added CFF support to the compression tools. Specifically, wrapping the font data in the WOFF 2.0 wrapper and compressing each table using LZMA. With the CFF support in place, we can now gather early compression improvement numbers for CFF fonts as well. Here for reference are the numbers for the Open Font Library (CFF) fonts: WOFF 2.0 Compression w/ Open Font Library (CFF) fonts https://docs.google.com/spreadsheet/ccc?key=0AvcH1ZzSrGMGdE93elRrWWp3TXRtdUNpa01kekhtc0E#gid=0 Average: 11.28% Median: 11.08% Stdev: 3.09% Min: 3.85% Max: 25.70% The second change updated the comparisons. Previously the tool compared the compression improvement of WOFF 2.0 over GZIP. Now the tool compares WOFF 1.0 and WOFF 2.0. While the difference between GZIP and WOFF 1.0 small, on the order of a couple hundred bytes, the WOFF 1.0 vs. 2.0 comparison is more relevant to advancing the specification. Thank you!
