    Part of what you are looking for is discussed in the Draft
    Unicode Technical Report #25, "Unicode Support for Mathematics".
    See Section 2.11 Geometric Shapes in that document.

    The discussion there is tentative, in part because there is
    still some controversy in the UTC regarding exactly which
    sets of characters line up in what sets of gradation for
    these geometric forms.

    You could provide feedback to the authors of the Draft UTR
    to help them figure out what questions should be addressed
    in that UTR regarding the geometric shape characters.
