can you test with
local function s_uncover(splitter,cache,cover)
if cover == "" then
return nil
else
local uncovered = cache[cover]
if not uncovered then
uncovered = lpegmatch(splitter,cover)
cache[cover] = uncovered
end
return { uncovered }
end
end
btw, what are features like cv80 and cv81 supposed to represent?

ok, so nothing really special.
Does fontforge already support these Feature Parameters tables? And
should we do something with them?

I'm not sure, but AFAIK our "snapshot" of FontForge predates all that
stuff.
