The good news is, Xft is hardly going to fail.
One can easily put "A quick brown fox jumps over the lazy dog" for
TitleFont into .twmrc as an amusing proof. So if XLFD loading fails, we
will in fact never enter the "fallback" branch in util.c in GetFont().
But anyways, on our adventurous path to save "fixed" I'll put up a one
more proposition. What about the following code fragment at the
beginning for GetFont() in util.c? Now "fixed", "variable", "7x13" et
cetera are fine as font names. :-)

void
GetFont(MyFont *font)

#ifdef TWM_USE_XFT
XFontStruct *xlfd;
Atom atom;
char *atom_name;
if (font->font != NULL) {
XftFontClose (dpy, font->font);
font->font = NULL;
}
/* test if core font: */
xlfd = XLoadQueryFont (dpy, font->name);
if (xlfd) {
if (XGetFontProperty (xlfd, XA_FONT, &atom) == True) {
atom_name = XGetAtomName (dpy, atom);
if (atom_name) {
font->font = XftFontOpenXlfd (dpy, Scr->screen, atom_name);
XFree (atom_name);
}
}
XFreeFont (dpy, xlfd);
}
/* next, try Xft font: */
if (font->font == NULL)
font->font = XftFontOpenName (dpy, Scr->screen, font->name);
/* fallback: */
....
