    It is best to avoid confusing mark positioning with kerning, since these
    are necessarily separate procedures. Horizontal spatial relationships
    between letters, including kerning (i.e. pair-specific adjustment of
    individual letter advance widths) needs be independent of mark
    positioning and, indeed, to ignore the presence of mark glyphs in the
    string (except in exceptional cases that are typeface-specific and need
    to be controlled at the font level).
