Universal Multiple-Octet Coded Character Set

Title: Regarding WG2 N3081, proposal for additions to Vai

There are obvious reasons for the addition of 10 Vai digits.
They seem to be attested historically and have been used at
some point, even though they aren't in normal use.

However, I don't understand the proposed addition of the 4 nasals:

	A501 VAI SYLLABLE EEN
	A525 VAI SYLLABLE IN
	A572 VAI SYLLABLE OON
	A596 VAI SYLLABLE UN

These nasals seem to be newly made-up characters for the purpose
of filling in a grid, and no attestation is provided for any of
them. As I read the discussion, they are proposed for addition
based on analogy to 1911 additions. But I see no evidence at all
that they are actually needed, merely assertions that they would
be "useful". There are other gaps in the syllabary -- why are these
four "special" in any way? I don't know of any encoding principle
that requires a syllabary to have its theoretical grid completely
filled. I would recommend that the committee proceed with caution
in considering this proposal.
