There is no definitive answer to that question. However, I sure
hope there is a definitive answer to the question "which Unicode
characters are allowed for a given language" *when used as
a label in the .COM zone*. For another example, the definitive list
of (additional) characters for a German label in the .DE zone is

http://www.denic.de/de/domains/idns/liste.html

On the other hand, a German label in the .CH zone is

http://www.switch.ch/de/id/faq/idn.html

which is a subset of the .DE list. I'm (now) certain that Verisign
has a definitive list of characters for a German label in the
.COM zone (and I expect this is the same list that DENIC uses,
as that is the superset of the Austrian and Swiss sets).
