IANA has added the "emodeng," "nulik," and "rigik" variant subtags to the language subtag registry. Please see

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.
