Abstract:
   If a protocol expects to compare two strings and is prepared only for
   those strings to be ASCII, then using Unicode codepoints in those
   string requires they be prepared somehow.  Internationalizing Domain
   Names in Applications (here called 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 needs to be designed.  This document outlines the issues
   to be faced by those designing a Stringprep replacement.
