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