As far as I can tell Pango does this fallback without any setup, not 
sure why you have all this code for turning on fallback. The following 
seems to produce all the assigned glyphs in just about every block I 
tried, and certainly produces glyphs that are not in sans:

   PangoFontDescription *font_description = pango_font_description_new ();
   pango_font_description_set_family (font_description, "sans");
   pango_font_description_set_weight (font_description, 
PANGO_WEIGHT_NORMAL);
   pango_font_description_set_absolute_size (font_description, 32 * 
PANGO_SCALE);
   PangoLayout *layout = pango_cairo_create_layout (cr);
   pango_layout_set_font_description (layout, font_description);
   pango_layout_set_markup (layout, text, -1);
   pango_layout_set_width(layout, (W-20) * PANGO_SCALE);
   pango_layout_set_height(layout, (H-100) * PANGO_SCALE);
   cairo_move_to (cr, 10.0, 100.0);
   pango_cairo_show_layout (cr, layout);
   g_object_unref (layout);
   pango_font_description_free (font_description);
