This paper was presented to the Unicode consortium by Dev Dass Manandhar et al. as an alternative to Anshuman Pandey's proposal (cited here: Proposal to Encode the Newar Script in ISO/IEC 10646). This proposal includes a set of breathy consonant characters with distinct encodings; Pandey's proposal analyses these characters as conjuncts. As of December 2013, agreement has yet to be reached as to which analysis is correct.
(With thanks to Pat Hall for notifying us of this proposal.)
