His writing there is pretty confusing. He started by complaining about a glyph that was missing until 2005, but was either fixed in 2005 or approximated by combining some characters 'ত + ্ + ‍ = ‍ৎ'. He doesn't really make it very clear whether ৎ is a substitute for a glyph, or whether it's the correct glyph and a case of an input system not making that easy to enter, but it seems like the glyph was added in 2005 and he's complaining about the input method. Assuming it is a case of a clunky input system, then pointing the finger at the Unicode consortium seems pretty weak, since so far as I understand it, various OS vendors/app platforms handle that implementation.
