Work in the IETF and other areas has exposed the general topic of Internationalization (i18n) as a very complex one,

with almost all decisions involving complex tradeoffs along multiple dimensions rather than “right” or “wrong” answers. The IAB intends to try to bring these issues together to reduce the number of decisions that are made on an isolated topic basis and, where appropriate, to review prior IAB and IETF work that has may require updating to reflect accumulated experience.
