They are enabled by default in the "generic" (Latin etc) engine, so
you'll get them unless you explicitly turn them off. It's hard to
think of any reason to do this, unless you wanted to demonstrate how
diacritics might appear in the absence of proper positioning support.
Try
% - - - -
\font\x="Charis SIL" at 12pt
\font\y="Charis SIL:-mark,-mkmk" at 12pt
\x
T^^^^0308^^^^0301h^^^^0303^^^^0320i^^^^0304^^^^0302s^^^^0324^^^^0325
is a test.
\y
T^^^^0308^^^^0301h^^^^0303^^^^0320i^^^^0304^^^^0302s^^^^0324^^^^0325
is a test.
\end
