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.

This document is a product of the Internationalized Domain Name
Working Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
