This draft is a work item of the Preparation and Comparison of Internationalized Strings of the IETF.

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

   Application protocols using Unicode code points in protocol strings
   need to properly handle such strings in order to enforce
   internationalization rules for strings placed in various protocol
   slots (such as addresses and identifiers) and 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, enforcement, and
   comparison of internationalized strings ("PRECIS") in a way that
   depends on the properties of Unicode code points and thus is more
   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).  This document obsoletes RFC 7564.
