   The framework for preparation, enforcement, and comparison of
   internationalized strings ("PRECIS") defines several classes of
   strings for use in application protocols.  Because many protocols
   perform case-sensitive or case-insensitive string comparison, it
   necessary to define methods for case mapping.  In addition, both the
   Internationalized Domain Names in Applications (IDNA) and the PRECIS
   problem statement describe mappings for internationalized strings
   that are not limited to case, but include width mapping and mapping
   of delimiters and other special characters that can be taken into
   consideration.  This document provides guidelines for designers of
   PRECIS profiles and describes several mappings that can be applied
   between receiving user input and passing permitted code points to
   internationalized protocols.  In particular, this document describes
   both locale-dependent and context-depending case mappings as well as
   additional mappings for delimiters and special characters.
