Abstract:
   Application protocols using Unicode code points in protocol strings
   need to properly prepare such strings in order to perform valid
   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
   PRECIS string classes or subclass the PRECIS string classes as
   needed.  This framework takes an approach similar to the revised
   internationalized domain names (IDNs) 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 the IAB's
   recommendations regarding IDNs (RFC 4690), albeit for application
   technologies other than the Domain Name System (DNS).  This document
   obsoletes RFC 3454.
