FYI If there are no objections I will try to advance this to RFC (Experimental) status in two weeks, then register "UTF-7". David Subject: I-D ACTION:draft-goldsmith-utf7-01.txt Sent: 2/5/97 6:42 AM Received: 2/5/97 11:06 AM From: Internet Drafts, Internet-Drafts@ietf.org To: IETF-Announce.@ietf.org; Enclosure: MIME file.4 A Revised Internet-Draft is available from the on-line Internet-Drafts directories. Title : A Mail-Safe Transformation Format of Unicode Author(s) : D. Goldsmith, M. Davis Filename : draft-goldsmith-utf7-01.txt Pages : 12 Date : 02/04/1997 The Unicode Standard, version 2.0, and ISO/IEC 10646-1:1993(E) (as amended) jointly define a character set (hereafter referred to as Unicode) which encompasses most of the world's writing systems. However, Internet mail (STD 11, RFC 822) currently supports only 7-bit US ASCII as a character set. MIME (RFC 1521 and RFC 1522) extends Internet mail to support different media types and character sets, and thus could support Unicode in mail messages. MIME neither defines Unicode as a permitted character set nor specifies how it would be encoded, although it does provide for the registration of additional character sets over time. This document describes a transformation format of Unicode that contains only 7-bit ASCII characters and is intended to be readable by humans in the limiting case that the document consists of characters from the US-ASCII repertoire. It also specifies how this transformation format is used in the context of MIME and RFC 1641, "Using Unicode with MIME". Internet-Drafts are available by anonymous FTP.

A URL for the Internet-Draft is: ftp://ds.internic.net/internet-drafts/draft-goldsmith-utf7-01.txt Internet-Drafts directories are located at: o Africa: ftp.is.co.za o Europe: ftp.nordu.net ftp.nis.garr.it o Pacific Rim: munnari.oz.au o US East Coast: ds.internic.net o US West Coast: ftp.isi.edu Internet-Drafts are also available by mail. Send a message to: mailserv@ds.internic.net. In the body type: "FILE /internet-drafts/draft-goldsmith-utf7-01.txt". NOTE: The mail server at ds.internic.net 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 Internet-Draft. --Boundary (ID uEbHHWxWEwCKT9wM3evJ5w)
