Thank you for confirming that.

When I install this from the package manager, I get a PostScript font,
not a TrueType font (you can verify that yourself with "fc-list 'Aharoni
CLM' file"). I don't know how PostScript fonts are handled by Emacs.
But, not surprisingly, it does not go through the FLT file that we have
been hacking on so far.
Note that AFAIK, PostScript fonts do not have the kind of metadata that
is needed for positioning individual glyphs as OpenType has, so all the
functionality comes from code. Still, Harfbuzz can do it, so in
principle, Emacs can, too. ;-)
