Solution for Extended Tamil

[Ken Whistler]

ccc=0 means that a character does not reorder for the canonical ordering 
part of the Unicode normalization algorithm. (See Canonical Ordering 
Algorithm in Section 3.11 in the core spec. 
https://www.unicode.org/versions/Unicode15.0.0/ch03.pdf#G49591) That 
sense of non-reordering has nothing to do with reordering (or 
non-reordering) of glyphs left and right for rendering of Indic scripts. 
It sounds like folks are talking past each other on this.
