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 
context.

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 
civimayam.

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.
