Thanks.  Maybe someone else will be able to show alternative greetings
in some other language(s) that use Devanagari, and we could then
decide how to proceed in this matter.

Btw, I'd like to clarify:

When I wrote that, I meant the name of the script as a symbol, which
we use in char-script-table, in font- and fontset-related settings,
and in other similar situations.  I did not mean the name that appears
in HELLO, where we already decided to use Odia, per its official name.
Making the change there doesn't affect user input in any way, it's
just a "display name" of the script, so to say.
