The following simple program prints char-by-char info on a XFLD
font. For GTK+ 1.2, it works fine. For my GTK+ 2.4.14/X.org
installation (FC3), it fails to provide any char-by-char info. It also
fails using GTK+1.2 on X.org.
Any clues why not? The font exists, but apparently without metrics.

int lbearing, rbearing, ch_width, ascent, descent;
gtk_init (&argc, &argv);
fprintf (stderr, "loading %s\n", argv[1]);
font = gdk_font_load (argv[1]);
if (!font)
return -1;
fprintf (stderr, "have font\n");
for (i = 0; i < 256; i++) {
text[0] = i;
gdk_text_extents (font, text, 1,
&lbearing, &rbearing, &ch_width, &ascent, &descent);
printf ("char[%d] = %d %d %d %d %d\n", i,
lbearing, rbearing, ch_width, ascent, descent);
}
return 0;
}
