[Gautam]: Yes, they do. The arrangement is identical
in a new code space of the same size.

[Gautam]: Nobody is objecting to the addition of these
forms, only to their placement vis-s-vis the other

[Gautam]: Yes, indeed. The ministry has been renamed.
TDIL remains the same.

[Gautam]: I did look up the document and this is what
"The Devanagari block of the Unicode Standard is based
on ISCII 1988. ...
The Unicode Standard encodes Devanagari characters in
the same relative positions as those coded in
positions A0-F4 in the ISCII 1988 standard. The same
character code layout is followed for eight other
Indic scripts in the Unicode Standard ... This
parallel code layout ... follows the stated intention
of the Indian coding standard to enable one-to-one
mappings between analogous coding positions in
different scripts in the family."
Clearly ISCII has a *lot to do* with code point
choices in the range U+09E0..U+09FF.
