what are the chances this could be written with a Lua callback?
I've thought about replacing all "---" by an em-dash and all "--" by an en-dash with a
"process_input_buffer" callback. But this won't work.
"process_input_buffer" is indeed a bad idea for such a replacement. But
it can be done while processing a node list: replace sequences of nodes
(e.g. two hyphen nodes) by something else (an en-dash). That's basically
how contextual ligatures are implemented (and even simple ligatures when
luaotfload is in "node" mode, if I remember correctly), so it's no big deal.
Best,
