Introduction

IDNA2008

This document is one of a collection that, together, describe the protocol and usage context for a revision of Internationalized Domain Names for Applications (IDNA) that was largely completed in 2008, known within the series and elsewhere as "IDNA2008". The series replaces an earlier version of IDNA [RFC3490] [RFC3491]. For convenience, that version of IDNA is referred to in these documents as "IDNA2003". The newer version continues to use the Punycode algorithm [RFC3492] and ACE (ASCII-compatible encoding) prefix from that earlier version. The document collection is described in Section 1.2. As indicated there, this document provides definitions and other material that are common to the set.
