    We have (at least) two issues going on here.

    1) Should existing conventions with regard to displaying
    combining marks without base characters be supported?

    2) Should rendering engines and fonts be designed to
    "correctly" display any combining mark on any base

    I answer "yes" to (1) and "no" to (2). Sorry for
    being unclear.

    Perhaps what is needed is a new range of characters
    supporting documented existing symbols. The first
    new character to be proposed should probably be a
    dotted circle, as this is a common method of display.

    Using U+25CC for this purpose is a "hack". It may be
    a good "hack", but it's still a "hack".

    The Unicode note for U+25CC says "note that the reference
    glyph for this *character* is intentionally larger than
    the dotted circle *glyph* used to indicate combining
    characters in this standard...". (Emphasis added.)

    It looks like there is currently no *character* in TUS
    which has the semantics we seek.

    Best regards,
