Title : Punycode: An encoding of Unocode for use with IDNA
Author(s) : A. Costello
Filename : draft-ietf-idn-punycode-02.txt
Date : 23-May-02
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 [UNICODE]
into an ASCII string [ASCII]. 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

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
