No. It is not a "script" as defined in ISO 15924.
But Unicode uses a Private Use Code for that,
which is proper.

No, it isn't. And your application for that code
contained no evidence as to what it referred to,
so we aren't doing anything about it until there
is more evidence. You will need to supply that in
the online proposal form, NOT on the general

Unicode can't do that (sensibly) until they are encoded.

This doesn't make any sense.

We seem to be doing that anyway.
