Dear Mr. Beckstrom,
In July 2000, CNNIC, JPNIC (now JPRS), KRNIC (now part of NIDA) and TWNIC jointly established Joint Engineering Team (JET) to develop and implement IDN technology. JET is responsible for drafting RFC 3743 that is commonly known as JET Guidelines for Chinese, Japanese and Korean IDN.
1) IDN Variant Problem. On 27th March 2003, ICANN Board endorsed the “Guidelines for the Implementation of Internationalized Domain Names” 1 with the following:
"3. In implementing the IDN standards, top-level domain registries will (a) associate each registered internationalized domain name with one language or set of languages, (b) employ language-specific registration and administration rules that are documented and publicly available, such as the reservation of all domain names with equivalent character variants in the languages associated with the registered domain name, and, (c) where the registry finds that the registration and administration rules for a given language would benefit from a character variants table, allow registrations in that language only when an appropriate table is available."
The implementation of IDN variant is of utmost importance to our community as variants are often used interchangeably, similar although not the same, as uppercase and lowercase characters in English.
JET would like to urge ICANN to implement TLD with IDN variants, at least for the Chinese, Japanese and Korean strings, in according to RFC 3743.
