You mean, it doesn't cause Emacs to obey set-fontset-font setting?  If
so, I don't know what's wrong; most probably there's something in this
complicated setup you didn't show, or maybe something that you did
show has some strange effect that I cannot spot.

In general, the character you tried to display belongs to the symbol
block, and Emacs by default uses the default face's font to display
it.  Setting use-default-font-for-symbols to nil disables that, and
Emacs should obey set-fontset-font.  That's all I know.
