Use of UCS as a common reference
UCS: Universal Character Set (Unicode/ISO 10646)
Allow documents to be encoded in various legacy encodings
Have documents/protocol declare document encodings (MIME "charset" parameter)
Define character escapes based on Unicode/ISO 10646
ꯍ in HTML 4.0/XML 1.0
easy transcoding
full UCS repertoire usable
Applications behave as if Unicode/ISO 10646 was used internally (RFC 2070 reference processing model, UCS as the document character set)
