IAB Thoughts on Encodings for Internationalized Domain Names
RFC 6055, “IAB Thoughts on Encodings for Internationalized Domain Names”, is an Informational document published in February 2011 by D. Thaler, J. Klensin, S. Cheshire. It updates RFC 2130. The canonical text is published by the RFC Editor.
Abstract
This document explores issues with Internationalized Domain Names (IDNs) that result from the use of various encoding schemes such as UTF-8 and the ASCII-Compatible Encoding produced by the Punycode algorithm. It focuses on the importance of agreeing on a single encoding and how complicated the state of affairs ends up being as a result of using different encodings today.
