There will be some differences; yes, but it should be near enough.

I does not work in that it doesn't give me the font I want.

Anyway, `load-font' almost gets me to where I want to be

(insert (propertize "FOO" 'face (list :font (open-font (find-font (font-spec :family "futura" :size 20))))))

gives me text with:

#<font-object "-adobe-Futura-ultrabold-normal-normal-*-2-*-*-*-*-0-iso10646-1">

That's pretty close, although the size is 2 instead of 20...  *sigh*

:size doesn't seem to have any effect at all here.

(font-info (find-font (font-spec :family "futura" :size 20)))
=>
["-adobe-Futura-ultrabold-normal-normal-*-2-*-*-*-*-0-iso10646-1" "Futura:pixelsize=2:foundry=adobe:weight=ultra-bold:slant=normal:width=normal:scalable=true" 2 4 0 0 0 1 3 1 1 1 "/usr/share/fonts/X11/Type1/pfud8a.pfa" (opentype)]

(font-spec :family "futura" :size 20)
=> #<font-spec nil nil futura nil nil nil nil nil 20 nil nil nil nil>

(find-font (font-spec :family "futura" :size 20))
=> #<font-entity xft adobe Futura nil iso10646-1 ultra-bold normal normal 0 nil nil 0 ((:font-entity "/usr/share/fonts/X11/Type1/pfud8a.pfa" . 0))>

So...  something got lost in the `find-font' call?

:font "futura:size=20" does not work.  If you mean

(insert (propertize "FOO" 'face (list :font "-adobe-Futura-ultrabold-normal-normal-*-20-*-*-*-*-0-iso10646-1")))

that doesn't work either.
