Hello John, As I understand language code (language tag) required to register multilingual domain name. Domain name must have characters only within one language and you must provide this language together with domain name, maybe registry check if characters of domain match to defined languages, don't know. Some registrars assign this tag to domain themselves, some, as Tucows does, require user to provide this code.
More about language tag here: http://www.verisign.com/nds/naming/idn/faq/langtag_faq.html BTW, can someone enlight me where I can find character tables for each language tag ? JK> When using the new IDN Conversion tool at the URL found in the recent JK> reseller update, it is possible to convert to and from Punycode without JK> specifying a "Language Code". But the new RCL code and the update to the JK> Horizon RWI has the "Language Code" option required when registering or JK> transferring a domain name of the IDN persuasion. What is the purpose of JK> this language code, as it seems one can do conversions to and from UTF-8 JK> without it? Is it actually the marker for an IDN, i.e. if the domain has JK> a language code it's an IDN? JK> IDNs, formerly known as multilingual domain names... "Internationalized JK> domain names" as if domain names were not previously international. -- Best regards, Sergei Kolodka [EMAIL PROTECTED]
