    Just to make sure everyone is clear on this, a coded character can have
    more than one meaning. Multiple interpretations is not necessarily a
    justfication to disunify.

    1. "Ambiguous" doesn't mean the character has no meaning. It means the
    character has multiple meanings, which cannot always be determined from

    2. Unicode doesn't define the meaning of characters such as this. It
    provides a code point, a reference glyph (which is not guaranteed to be
    the most appropriate glyph for all use cases), a set of properties that
    help computer implementations make decisions on rendering and breaking
    and collation and such, and an optional set of *informative* usage
    notes. Unicode does not state whether U+0BF3 may or may not be used for

    Probably you would need to find the different shapes in contrast with
    one another (i.e. in the same document).

    The "solution" might simply be for someone from UTC to state that U+0BF3
    should be used for civamayam. Evidently Tamils don't have any trouble
    telling which usage of this glyph is intended.
