    No, they do not. For instance, in recent versions of Times New Roman, you
    will find 208 glyphs that are not encoded at some code point. They are
    accessible via lookup rules in various OpenType tables within the font,
    but not via the cmap table (it's the cmap that determines what is directly
    encoded at some code point).
