it depends on the implementation, as one can map a character anywhere
and U+F0XXXX is unlikely to be a glyph index and therefore of not much
information; at the engine end the index is known ((part of the char
data) so I can imagine mentioning both as option U+XXXXX [I+YYYY] or
something like that
eventually all messages will be revisioned and then a macro package can
add extra info
((
we can consider an intermediate resolver callback
callback.register("glyphinfo", function(f,c)
-- f == font id, c = glyph number
return "whatever you want injected"
end)
))
