Backed out
changeset f9f71cccb5c3 - Wuzzy is right, the license is incompatible.
I'd misread the wording on https://fontlibrary.org/en/font/symbola
The terms on the author's site prevent using it with almost all FOSS projects, and even prevent using it in a merge like this.
We'll just have to find some other font to improve coverage.
