I use something like this to get the character size in a GtkTextView:

get_char_size(GtkWidget *widget, gint *char_height, gint *char_width)
{
  PangoLayout    *layout;
  PangoRectangle  logical_rect;

  layout = gtk_widget_create_pango_layout(widget, "W");
  pango_layout_get_pixel_extents(layout, NULL, &logical_rect);
  *char_height = logical_rect.height;
  *char_width  = logical_rect.width;

  g_object_unref(layout);
}

But I use fixed-width fonts. With variable-width fonts the problem is
more complicated.
