Title: Punycode: A Bootstring encoding of Unicode for Internationalized Domain Names in Applications (IDNA)
State: Pending
Authors: Adam Costello
Group: Individual Submissions (none)
Date: 2004-04-15
Punycode is a simple and efficient transfer encoding syntax designed for
use with Internationalized Domain Names in Applications (IDNA). It uniquely
and reversibly transforms a Unicode string into an ASCII string. ASCII
characters in the Unicode string are represented literally, and non-ASCII
characters are represented by ASCII characters that are allowed in host
name labels (letters, digits, and hyphens). This document defines a general
algorithm called Bootstring that allows a string of basic code points to
uniquely represent any string of code points drawn from a larger set.
Punycode is an instance of Bootstring that uses particular parameter values
specified by this document, appropriate for IDNA.
