MIME Part Two: Message Header Extensions for Non-ASCII Text
RFC 1522, “MIME Part Two: Message Header Extensions for Non-ASCII Text”, is a Draft Standard document published in September 1993 by K. Moore. It obsoletes RFC 1342. It has been obsoleted by RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC 2049 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This memo describes an extension to the message format defined in RFC 1521, to allow the representation of character sets other than ASCII in RFC 822 (STD 11) message headers. The extensions described were designed to be highly compatible with existing Internet mail handling software, and to be easily implemented in mail readers that support RFC 1521.
What “Draft Standard” means
A historical maturity level (retired in 2011) that sat between Proposed Standard and Internet Standard and required multiple interoperable implementations.
