Verisign - Allowable characters

[andre]

Been looking at http://www.verisigninc.com/assets/languagefiles/CHI.html which lists all the Chinese characters allowable when registering a Chinese IDN with Verisign.

I notice that

For the CJK Compatibility Ideographs unicode block only the single character U+FA20 﨨 is allowed
None of the Unicode SIP (Supplementary Ideographic Plane) chinese characters are allowed


Thoughts?

I think the use of char tables might be deprecated now that IDNA2008 exists (?)

IDNA2008 specifies allowed codepoints while IDNA2003 specifies disallowed codepoints (i.e. everything else is allowed by default in IDNA2003).

Yes, but those tables have sort of morphed into Variants. The earlier work is the basis for the current work on Variants.

I think they still have to say what character groups/scripts the TLD will support.

I had this very helpful response from Verisign:-

Verisign's CJK policy is driven by data tables provided by appropriate authorities. For instance, CNNIC provides a table which limits the characters that can be used in a Chinese (CHI) domain name. The only Compatibility Ideograph currently allowed in a Chinese domain is U+FA28. Again, this information is based on Chinese tables provided by CNNIC.

So now I just need to ask CNNIC the same questions :)

that explains it I think :

I don't think CNNIC was much concerned about characters from non Mandarin languages (Cantonese most notably).
