37 Clarification of the Use of Zero Width Joiner in Indic Scripts
2004.08.03 There are some inconsistencies in the use of ZERO WIDTH
JOINER (ZWJ) in a number of Indic scripts which are outlined in the
accompanying review document. This proposal intends to rectify these
problems, clarifying how the ZERO WIDTH JOINER is to be applied in
scripts, and consolidating common mechanisms for equivalent problems
that exist in several scripts. The scope for what is proposed covers
Devanagari, Bengali, Gurmukhi, Gujarati, Oriya, Tamil, Telugu, Kannada
and Malayalam. The question for reviewers is: Should the UTC adopt a
model in which ZWJ precedes Virama, as proposed in section 7 of the
review document?

Resolution: Closed 2004-08-24. UTC accepted the proposal and will create
an Indic conjoining behavior model.
