Until now, there has been no standard way for host names to use characters outside the ASCII repertoire. This document describes a mechanism called IDNA that enables internationalized host names, that is, host names that use characters drawn from a much larger repertoire. (The "D" in the name originally stood for "domain", but the work is actually focused on host names, so the word "host" is used throughout this document.)
