This here works for me on texlive 2017:
Your suggestion works fine for me also with fonts which do have the needed diacritics (acute accent ^^^^0301 in my example), but fails otherwise: this happens for instance with the Georgia font. My concern is about French and fonts which have all the precomposed characters used in French (àâéèêëîïôûùç lower and uppercase) built-in. Fonts not satisfying this criteria (relying on composite characters only) would probably not provide correct hyphenation anyway. So another approach could be to build a table of possible composite characters for a given language and a Lua function which would replace each composite char found in the node list and belonging to the table (f.i. e^^^^0301) by the corresponding precomposed char (é) or warn if the replacement doesn't exist in the current output font. Does something like this exist already? Thanks, -- Daniel Flipo
