And what I should do about the "return new_kern(kern)"?
I tried various variants and got results from no letterspacing to
"invalid node type id" to " This can't happen (invalid node found in
discretionary)." to a luatex crash:
-- UF changed 2017-07-14
local new = node.direct.new
local kern_injector = function (fillup, kern)
if fillup then
local g = new("glue")
setfield(g, "stretch", kern)
setfield(g, "stretch_order", 1)
return g
end
--return new_kern(kern) --??

end
