Tools for handling TTF and WOFF2 ================================ https://fr.wikipedia.org/wiki/Web_Open_Font_Format_2 Print info about a TTF ---------------------- $ sudo apt-get install fontconfig $ fc-query ./2017-11-13-OpenSans-Regular.ttf => The "lang" and the "capability" are interesting to know the supported language. "en" and "otlayout:latn" are a must. Get version of a TTF -------------------- $ fc-query -f '%{fontversion}\n' ./OpenSans/2017-11-13-OpenSans-Regular.ttf | \ grep -v 'id' | perl -E 'printf "%.3f\n", <>/65536.0' => "1.100" indicates version "1.1" Source: https://stackoverflow.com/a/43614521/881731 Conversion from TTF to WOFF2 ---------------------------- $ sudo apt install woff2 $ woff2_compress 2017-11-13-OpenSans-Regular.ttf Source: https://dev.to/benjaminblack/converting-ttf-fonts-to-woff2-and-woff-3f5b OpenSans ======== General information ------------------- Official repository: https://github.com/googlefonts/opensans/tree/master/ License: Apache License 2.0 Google Fonts: https://fonts.google.com/specimen/Open+Sans#license Google CDN: https://fonts.googleapis.com/css?family=Open+Sans Debian package: $ sudo apt-get install fonts-open-sans $ ls -l /usr/share/fonts/truetype/open-sans/ Playing with the CDN -------------------- To fetch the WOFF2 from CDN (selecting WOFF2 instead of TTF is done by setting the HTTP Header User-Agent): $ cd /tmp $ curl -H 'User-Agent: AppleWebKit/537 Chrome/85' 'https://fonts.googleapis.com/css?family=Open+Sans' => The "latin" section is what we're looking for $ wget https://fonts.gstatic.com/s/opensans/v18/mem8YaGs126MiZpBA-UFVZ0b.woff2 To fetch the TTF from CDN: $ curl 'https://fonts.googleapis.com/css?family=Open+Sans' $ wget https://fonts.gstatic.com/s/opensans/v18/mem8YaGs126MiZpBA-UFVZ0e.ttf $ woff2_compress mem8YaGs126MiZpBA-UFVZ0e.ttf $ diff -s ./mem8YaGs126MiZpBA-UFVZ0e.woff2 ./mem8YaGs126MiZpBA-UFVZ0b.woff2 => The files are identical As of 2020-11-19, the version of the TTF is "1.101": $ fc-query -f '%{fontversion}\n' ./mem8YaGs126MiZpBA-UFVZ0e.ttf | \ grep -v 'id' | perl -E 'printf "%.3f\n", <>/65536.0' Generation of the "./OpenSans" folder ------------------------------------- $ mkdir ./OpenSans $ cd ./OpenSans $ REVISION=c0d8ce7dd46291a5d429ac537ddcd3617f4dc229 $ wget https://github.com/googlefonts/opensans/raw/master/LICENSE.txt $ curl https://raw.githubusercontent.com/googlefonts/opensans/${REVISION}/ttfs/OpenSans-Regular.ttf > 2017-11-13-OpenSans-Regular.ttf $ woff2_compress 2017-11-13-OpenSans-Regular.ttf => Note that the version of the TTF font is "2.010" (so more recent than the font on Google Fonts CDN)
