While meaningful variations would be sparse, meaningful
capitalization of Latin is also sparse. That is, meaningful
capitalization of "mydomain" should be

	myDomain
	Mydomain
	MyDomain
	MYDOMAIN

However, meaningless capitalization such as:

	mYdOmAiN

should also be protected, which should be same for Arabic.

A protection could be rejection of domain registration. But it,
anyway, requires a document of complete and unambiguous
definition of extended case insensitivities.

And, the definition used for TLDs must be international one.

So, the requirement for complete and unambiguous specification
for case insensitivities or canonicalization is same.

You seems to be thinking "variant" for Chinese mean simplified
and complex. But there are other types of "variant" Chinese
characters. It's somewhat like plain 'C' without ceddille and
'C' with ceddille, which, sometimes (here is dependency on
locale information), must be treated as identical characters.

They should, naturally, reject meaningless combinations.
