The subject I put to the bug report maybe imprecise actually.

What is lost or maybe not taken into account is the :family parameter in
the face.

Characters are inserted this way :

#(" - apache" 0 1 (face (:family "all-the-icons" :height 2.4) display
(raise -0.24) rear-nonsticky t font-lock-ignore t))

with the square being \xe909 .

The family is taken into account if I do :

(message #(" - apache" 0 1 (face (:family "all-the-icons" :height 2.4)
display (raise -0.24) rear-nonsticky t font-lock-ignore t)))

iie the glyph is displayed in the minibuffer, but not if I do

(insert #(" - apache" 0 1 (face (:family "all-the-icons" :height 2.4)
display (raise -0.24) rear-nonsticky t font-lock-ignore t)))

in the *scratch* buffer.

Does that help ?
