In font-ini.mkiv you can find

   liga=yes,kern=yes,tlig=yes,trep=yes] % texligatures=yes,texquotes=yes

You can find those features defined in font-otc.lua, but in short:
trep is responsible for auto-replacing 0x0027 into 0x2019. If you want
to disable that behaviour, you need to turn trep feature off, for
example with
    \definefontfeature[default][liga=yes,kern=yes,tlig=yes] % trep=no
to be more explicit

Sometimes you need to load the font after redefining the features, but
I'm not sure when that is and maybe I'm wrong (it might be true for
Type1 fonts or I may be wrong completely).


PS: just as a thought ... it might make sense to map 0x27 to some
(constant) private range slot and make it accessible with some control
sequence. I don't know to what extent that would be usable though, so
maybe that's just a way too silly idea.
