I tried reproducing this (starting from -Q), but I'm not sure whether
I'm doing it right.  First I evaled:

(set-fontset-font "fontset-default" nil
                  (font-spec :size 80 :name "Unifont Upper"))


Then inserted SMILING FACE WITH SMILING EYES AND THREE HEARTS (which
uses that font), and I got:

    ftcrhb:-PfEd-Unifont Upper-normal-normal-normal-*-80-*-*-*-d-0-iso10646-1 
(#x2886)

Character code properties: customize what to show
  name: SMILING FACE WITH SMILING EYES AND THREE HEARTS

So it seems to work for me.  Has this bug gone away in the meanwhile, or
are you still seeing it?
