    I don't like the look of this one. It might work as a kludge, but surely
    we should not encourage kludges in which the glyph (or non-glyph in this
    case) for one character, SPACE, is used with the code point of another
    character, U+25CC. This would cause considerable confusion for those
    deliberately trying to insert U+25CC, perhaps because they want to
    display the combining mark with a dotted circle.
