You can specify any default you wan't, including another type.  So you 
can say that the default is a XtRFontStruct intead of a XtRString.  
Then you can set the default to NULL and check against that.  When the 
code sees NULL, you extract the default font with XtConvert by giving 
it "XtDefaultFont"/"XtDefaultFontSet".

I'm not sure.  It is possible some older VMS or other systems still 
have X11R3 or X11R4 (not exactly sure when I18N became available).  
X11R5 and X11R6 do have it, which probably accounts for the majority of 
system nowdays (for example all versions of XFree86 and xorg, and 
Solaris back to 2.5 at least).

It depends on your font path.  XtDefaultFont, if no font is specified 
in .Xdefaults or any app-defaults file, is:
    f = XLoadFont(display, "-*-*-*-R-*-*-*-120-*-*-*-*-ISO8859-*");
but XtDefaultFontSet is
    f = XCreateFontSet(display, "-*-*-*-R-*-*-*-120-*-*-*-*,*",

(note no ISO8859 in the latter case).  For me that gives different 
matches, for you it may give the same font.  Since more locales specify 
UTF-8 nowdays I think a difference will not be uncommon.
