    For the purpose of my discussion, the meta aspects of character encoding
    in general (worthy of standardization, character not glyph, etc.) are
    all assumed to apply in the sense that it is assumed that the question
    that is left is the one of deciding the unification issues. Dragging
    these other aspects in doesn't help in getting clarity on how to settle
    the unification question in such cases. However, nobody suggests that
    they can be ignored when actually evaluating a specific proposal for

    Having said this, the result of the discussion so far points to a
    clarification of a key precedent in deciding the unification question:
    combining sequences are not used in Latin/Greek/Cyrillic and
    typographically related scripts, if the resulting shape would be fused
    (hook, bar, middle tilde, or other connected decoration).

    Resolving that this precedent does apply to decorated combining marks is
    itself enough to make this discussion useful, even if we were to reject
    the specific character later on some other grounds.
