That would avoid having to (re)define all the > main/sans/mono/math families. I agree that defining fallbacks for each font family is inconvenient. Defining font per script resembles specifying fonts per language in babel configuration, however fallback should work without explicit switching of language. I have seen that babel may determine language from character code points, but I have not tried if it works reliable and if it affects performance (as it does for fallback fonts). Maybe I did not read the manual with enough attention, maybe I tried it with too old version of LuaTeX, but I had a problem with Emoji. Depending on font such symbols either broke compilation or did not appear in PDF (accordingly to pdffonts font was embedded, text may be copied, but PDF viewers displayed blank space). https://list.orgmode.org/orgmode/scuirf$m7o$1@ciao.gmane.io/ Maxim Nikulin.
