Full internationalization of electronic mail requires not only the
capabilities to transmit non-ASCII content, to encode selected
information in specific header fields, and to use non-ASCII
characters in envelope addresses.  It also requires being able to
express those addresses and the information based on them in mail
header fields.  This document specifies an experimental variant of
Internet mail that permits the use of Unicode encoded in UTF-8,
rather than ASCII, as the base form for Internet email header field.
This form is permitted in transmission only if authorized by an SMTP
extension, as specified in an associated specification.  This
specification Updates section 6.4 of RFC 2045 to conform with the
requirements.  This memo defines an Experimental Protocol for the Internet
