    The difference is that the font/font engine needs to anticipate
    that the combination will be desired. Please see attached graphic.
    Without positioning rules, where should COMBINING CANDRABINDU go?

    Does it make a little hat for our guy? Should it be centered, or
    cocked to one side? Should it overlay and "turn that frown
    upside down" and give him a nose to boot?

    I agree that existing conventions should be supported.
