Abstract
This report details the conclusions of an IAB-sponsored invitational
workshop held 29 February - 1 March, 1996, to discuss the use of
character sets on the Internet. It motivates the need to have
character set handling in Internet protocols which transmit text,
provides a conceptual framework for specifying character sets,
recommends the use of MIME tagging for transmitted text, recommends a
default character set *without* stating that there is no need for
other character sets, and makes a series of recommendations to the
IAB, IANA, and the IESG for furthering the integration of the
character set framework into text transmission protocols.
0: Executive summary
The term 'Character Set' means many things to many people. Even the
MIME registry of character sets registers items that have great
differences in semantics and applicability. This workshop provides
guidance to the IAB and IETF about the use of character sets on the
Internet and provides a common framework for interoperability between
the many characters in use there.
The framework consists of four components: an architecture model,
which specifies components necessary for on-the-wire transmission of
text; recommendations for tagging transmitted (and stored) text;
recommended defaults for each level of the model; and a set of
