You should use the normal p(rint) command for xftfont
because it is not a Lisp object. But, if "pp xftfont" shows
0, xftfont is actually NULL.

Hmmm, it seems that there's something wrong in you Xft (or
underlying fontconfig/freetype)
Please compile the attached program and run it (as below).
What is shown?
% gcc `pkg-config --cflags xft` `pkg-config --libs xft` -o xfttest xfttest.c
% ./xfttest /usr/openwin/lib/X11/fonts/75dpi/courR14.pcf.Z
