 Confirming: all gtk2 apps silently skips ff ligature.

 Xaw, tcl/tk, Qt, gtk3 are fine.
 Strange  situtation with libreoffice: apparently the same libre-
office 4.3.3.2, Build ID 430m0(Build:  2),  from  debian  Jessie,
package    Installed:  1:4.3.3-2+deb8u5,  works from one computer
and skips ff from the other, on the same X server.
 links browser skips ff, but it apparently does not  have  it  in
it's font (answer from Xutf8LookupString is fine).

 Promille is fine in all of the above, including gtk2 apps.

 Motif  and  xforms  shows  german  ss ligature, but emits single
(last entered) f instead of ff ligature and single (last entered)
o instead of promille ligature.
