All true - but "so what?". This is an official policy what characters
can be used in a "German" domain name, in the .de zone. Whether that
makes it a "language table", I don't care. This kind of table is what
we have been talking about all along.

This is not the point. The point was your claim: "there cannot be an
official table", and I'm merely trying to say "but there is". Now,
I see that you make a difference between a character table for a
language, and a "language table"; I was unaware that "language table"
is a reserved term.

But we are not talking about typesetting here: this is about DNS.
