Oh, I was just asking about

luatexbase.add_to_callback("process_input_bu=
ffer", blabla, "blabla" )

and

=

luatexbase.remove_from_callback<=
span class=3D"gmail-pun">("process_in=
put_buffer", "blabla" )
=

LuaLaTeX users do that way=
 and I want to be sure it won't interfere with ConTeXt way of doing thi=
ngs so I can play with the suggestion made by Luigi.

You mean "Does context use callbacks?" You can bet on that. It is= how we
came to implementing callbacks (over a decade ago now, Taco and I spend quite some time exploring all these things in the process of luatex dev ... fond memories and so).

I don't know what latex does but context doesn't do much input
processing apart from some unicode related juggling. There are plenty of ways to hook in additional processing but there are multiple ways to
solve problems. Most of these mechanism in context are already pretty
old and hardly change.
