    I mean a character with a general category Lo and other character
    properties typical of a letter, though with neutral directionality. The
    representative glyph would have advance but no ink; valid font
    implementations could have ink -- e.g. a hyphen or asterisk -- and could
    offer alternate glyphs (using font features). Because glyphs *could*
    have ink, I would not call this "invisible letter"; something like
    "ellipsis letter" would be more appropriate.
