Because to convert the main tex file, I need to put a function in the 
callback process_input_buffer, and it converts everything from latin1 to 
utf, so if I want to have a file in utf, I need to convert it first 
(before it is processed in process_input_buffer) in latin1, and then (in 
process_input_buffer) convert it again to utf. If there is another 
solution than the process_input_buffer to convert the main tex file, I 
take it though...

I might have found a better solution that (unexpectedly) works: calling 
inputenc after lua-inputenc... it works fine for my tests: it uses the 
LICR, so when it reads the file again, no problem, but I need to test it 
more... If it works, I'll take this solution, as my aim is to emulate 
the old inputenc, not creating a new one with new aux files encoding 
conventions. I think people who want to do new things with LuaTeX must 
be workin in UTF-8, not using my packet (that will work for them too 
anyway).
