    For math, you're right. But I would still not say that using
    super- or subscript digits in cases like H₂O, m², ¹⁴C, or 10²³
    is even remotely wrong and should use markup instead. That
    would be quite unnecessary overkill, when font coverage of
    these characters is quite sufficient (and survives markup
    stripping, though not compatibility mapping; hoping that
    my examples will survive e-mail).
