I didn't know about these options, thanks

could there be a -7bit option to luatex for matters of \write ?

else packages from the pre-scantokens pre-detokenize area which
rely on external file output+input might be broken in certain
circumstances (I dont' have anything specific in mind, this is
pure rhetoric)

and about the \scantokens issue

the tracker


displays the topic as open

is there anything in the works ?
