    I'd agree it was not very common. If I recall, it was about when I was
    at school that the use of bold italic for vector variables became a
    normative standard.

    That, if I may say so, is a rather silly question, and also
    irrelevant. It's silly because no one mathematical notation is
    necessary - there's always another way to do it. For example, in
    school texts, and even in some monographs, you may see "bold" letters
    marked with the manuscript sign of under-tilde, instead of or as well
    as actually being bold. It's irrelevant, because it is not the
    business of Unicode to tell mathematicians what they should or should
    not do, any more than it is the business of Unicode to tell Swedes
    that they can just write "aa" instead of "", or Germans that they can
    just write "ae" instead of "".
