This is part of a function using GTK+/Pango that checks for presence of 
glyphs:

  PangoContext         *context;
  PangoFontDescription *fontdesc;
  PangoFont            *font;
  PangoCoverage        *coverage;

  context = gtk_widget_get_pango_context(GTK_WIDGET(gui->txtView));
  fontdesc = pango_font_description_from_string(gui->world->terminalfont);
  font = pango_context_load_font(context, fontdesc);
  coverage = pango_font_get_coverage(font,
                                     pango_context_get_language(context));

  /* U+25C6 BLACK DIAMOND */
  gui->ta.sup_geom_shapes   = pango_coverage_get(coverage, 0x25C6);

  pango_font_description_free(fontdesc);
  pango_coverage_unref(coverage);


Figuring out how to make a complete program out of it is left as an 
exercise to the reader.
