          An Encoding Parameter for HTTP Basic Authentication
                  draft-ietf-httpauth-basicauth-enc-00

Abstract

   The "Basic" authentication scheme defined in RFC 2617 does not
   properly define how to treat non-ASCII characters.  This has lead to
   a situation where user agent implementations disagree, and servers
   make different assumptions based on the locales they are running in.
   There is little interoperability for the non-ASCII characters in the
   ISO-8859-1 character set, and even less interoperability for any
   characters beyond that.

   This document defines a backwards-compatible extension to "Basic",
   specifying the server's character encoding expectation, using a new
   authentication scheme parameter.
