Title : PRECIS Framework: Preparation and Comparison of
Internationalized Strings in Application Protocols

Abstract:
Application protocols using Unicode code points in protocol strings
need to prepare such strings in order to perform comparison
operations (e.g., for purposes of authentication or authorization).
This document defines a framework enabling application protocols to
perform the preparation and comparison of internationalized strings
(a.k.a. "PRECIS") in a way that depends on the properties of Unicode
code points and thus is agile with respect to versions of Unicode.
As a result, this framework provides a more sustainable approach to
the handling of internationalized strings than the previous
framework, known as Stringprep (RFC 3454). A specification that
reuses this framework can either directly use the base string classes
or subclass the base string classes as needed. This framework takes
an approach similar to the revised internationalized domain names in
applications (IDNA) technology (RFC 5890, RFC 5891, RFC 5892, RFC
5893, RFC 5894) and thus adheres to the high-level design goals
described in RFC 4690, albeit for application technologies other than
the Domain Name System (DNS). This document obsoletes RFC 3454.
