    Obviously, if the font doesn't have the proper glyph, it can either display some
    fallback glyph(s) or display nothing. For ligatures, the obvious "fallback" behavior
    is, of course, to display separate glyphs. What bugs me however, is that in most
    cases even sequences like <a ZWJ e> and <o ZWJ e> are rendered as separate glyphs,
    even though the vast majority of fonts *does* have proper glyphs for those.
