Domain NamesFor years there were a lot of problems that existed with multibyte domain names (see below), that were mainly the result of the legacy of the internet infrastructure. End 1990s International Domain Names were proposed however it wasn't until 2009 that the ICANN approved the creation of internationalized country code top-level domains (IDN ccTLDs).
TLD for Asian Countries :
Some of the problems that had to be resolved when using non-latin letters are :
- some characters look the same but have different meaning
- some languages have optional characters (hebrew) and are they meaningfull for dns ?
- some scripts see accented letters as one some see it as composition of 2 elements
- problem with encodings (support, conversion)
- resolving the address must work in 2 ways : www.foo.cn and cn.foo.wwww
- some punctuation symbols have local alternatives : "." in an IME is often represented as a "。" so should there be support for both or only one of them ?
- should traditional input be converted to simplified input ? or should it be 2 different domains. but what with simplified characters that represent several traditional characters
