using luainputenc (and so disabling luatex's support for utf8) is hitting
the missing character
with a very large sledgehammer.

In luatex you could use the virtual font support to essentially add the
missing characters as virtual entries or just use the classic tex technique
of active characters.

\catcode"2014\active
\def^^^^2014{whatever you want to fake a dash with}
