Glyph attribution
Every glyph in Essenfont is traceable to its donor font. The build pipeline records which donor contributed each codepoint, and this mapping is available as cp_map.json in each GitHub Release.
The donor registry lists all 38 source fonts and their license terms. For the full per-codepoint attribution, download the release and inspect cp_map.json.
Reproducibility
The build is fully reproducible from the committed manifest:
git clone https://github.com/essenfont/essenfont
cd essenfont
bundle install
FONTISAN_PATH=../fontist/fontisan bundle exec ruby scripts/build.rb --format=otc-cff2
