I've made a new installation of Emacs (from the repository with pacman) and I've noticed that m17n-db and
libotf are installed implicitly (because of dependency) with Emacs.
Could this cause a problem with Harfbuzz (which is also installed implicitly with Emacs)?

I don't think so.

Start Emacs as "emacs -Q", then type "C-u C-x =" with point on some
character in the *scratch* buffer, and look at the line which says

              display: by this font (glyph code)

What does the following line say?
