IANA has added the "emodeng," "nulik," and "rigik" variant subtags to the language subtag registry. Please see http://www.iana.org/assignments/language-subtag-registry http://www.iana.org/assignments/lang-subtags-templates/index.html In addition, an encoding error I inadvertently introduced this month has been corrected. I apologize for any inconvenience this may have caused. If you have any questions about or otherwise wish to discuss this issue, you can reach me and/or IANA's IETF Liaison Michelle Cotton at iana@iana.org<mailto:iana@iana.org>. Best regards, Amanda Baber IANA Analyst ICANN
