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.

-- Library for parameters handling

params = {}

function parseParams()
    if ScriptParam ~= nil then
        for k, v in string.gmatch(ScriptParam, "(%w+)=([^,]+)") do
            params[k] = v
        end
    end
end
