    Good an example of flat and wide diacritics stacking. Just like I claimed.

    Vietnamese has the circumflex and accent not stacking but half-ways
    stacking. Looks like the case of where you have one flat and wide and
    one tall and narrow, you get a range of behaviors.

    Not clear that this has to be done in plain text. If different languages
    / notations have different *preferences* it's not clear that these
    preferences *must* be presentable in plain text. They would look a bit
    odd, perhaps, but not be ambiguous.

    Rendering engines should be prepared to allow all modes of stacking, and
    CSS or similar protocols might need commands to set the preferred
    stacking mode, but as difficult as this would be to get support for, it
    still does not make a hard and fast case for this to be solved on the
    encoding level.
