ok, the case when it's not in the font is easy to fix by a slightly
different test (aroun dline 4500 in font-otf.lua)
local chardata = characters[char]
if chardata and chardata.description.class == "mark" then
set_attribute(current,state,5) -- mark
if trace then fcs(current,"font:mark") end
elseif isol[char] then -- can be zwj or zwnj too
.....
you need to remake the format
the problem of the glyph showing up ... i have to think of an option
(because i guess that sometimes it's handy for tracing)
