See RFC 3932 for more information. Abstract Many Chinese characters in common use have variants, which makes most of the Chinese Domain Names (CDNs) have at least two different forms. The equivalence between Simplified Chinese (SC) and Traditional Chinese (TC) characters is very important for CDN registration. This memo builds on the basic concepts, general guidelines, and framework of RFC 3743 to specify proposed registration and administration procedures for Chinese domain names. The document provides the information needed for understanding and using the tables defined in the IANA table registrations for Simplified and Traditional Chinese. Lee, et al.

Introduction With the standardization of Internationalized Domain Names for Application (IDNA, described in [RFC3490], [RFC3491], and [RFC3492]), internationalized domain names (IDNs), i.e., those that contain non- ASCII characters, are included in the DNS, and users can access the Internet with their native languages, most of which are not English. However, many languages have special requirements, which are not addressed in the IDNA RFCs. One way to deal with some of the remaining issues involves grouping characters that could be confused together as "variants". The variant approach is discussed in RFC 4290 [RFC4290] and specifically for documents written in Chinese, Japanese, or Korean (CJK documents), in the so-called "JET Guidelines" RFC 3743 [RFC3743]. Readers of this document are assumed to be familiar with the concepts and terminology of the latter. The guidelines specified in this document provide a set of specific tables and methods required to apply the JET Guidelines to Chinese characters. For example, changes were made in the forms of a large number of Chinese characters during the last century to simplify writing and reading. These "Simplified" characters have been adopted in some Chinese-speaking communities, while others continue to use the "Traditional" forms. On the global Internet, if IDNA were used alone, there would be considerable potential for confusion if the two forms were not considered together. Consequently, effective use ofShow full document text
