Title : Stringprep Revision Problem Statement
Author(s) : M. Blanchet, A. Sullivan
Filename : draft-ietf-precis-problem-statement-00.txt
Pages : 12
Date : 2010-10-18
Using Unicode codepoints in protocol strings that expect comparison
with other strings [[anchor1: The WG will need to decide whether
"other strings" is too broad. In particular, what about protocol
slots that can take strings other than plain ASCII?
--ajs@shinkuro.com]] requires preparation of the string that contains
the Unicode codepoints. Internationalizing Domain Names in
Applications (IDNA2003) defined and used Stringprep and Nameprep.
Other protocols subsequently defined Stringprep profiles. A new
approach different from Stringprep and Nameprep is used for a
revision of IDNA2003 (called IDNA2008). Other Stringprep profiles
need to be similarly updated or a replacement of Stringprep need to
be designed. This document outlines the issues to be faced by those
designing a Stringprep replacement.
