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.

This document is a product of the Preparation and Comparison of Internationalized Strings Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
