The IESG has approved Preparation of Internationalized Strings
('stringprep') <draft-hoffman-stringprep-07.txt> as a Proposed
Standard. This document is the product of the IDN Working Group.The IESG contact persons are Erik Nordmark and Thomas Narten. Technical Summary This document describes a framework for preparing Unicode text strings in order to increase the likelihood that string input and string comparison work in ways that make sense for typical users throughout the world. The stringprep protocol is useful for protocol identifier values, company and personal names, internationalized domain names, and other text strings. This document does not specify how protocols should prepare text strings. Protocols must create profiles of stringprep in order to fully specify the processing options. This document can be when protocols need a mechanism to compare identifiers that use Unicode. One use is for IDN, but there are other potential uses for IP storage, Kerberos, etc. Working Group Summary The working group resolved two major comments in response to the IETF last call (plus minor and editorial comments). The major comments where - change from using Unicode 3.1 to 3.2 - added restrictions for bidirectional characters A new WG last call was done on these changes. There was WG concensus to advance this document. Protocol Quality This document has been reviewed for the IESG by Erik Nordmark. RFC Editor Note: In section 3.2 change: Authors of profiles of this document need to consider the effects of changing the mapping of any currently-assigned character when updating their profiles. Adding a new mapping for a currently-assigned character, or changing an existing mapping, could change the behavior that users see in both systems that have been updated and systems that have not been updated. to read: Authors of profiles of this document need to consider the effects of changing the mapping of any currently-assigned character when updating their profiles. Adding a new mapping for a currently-assigned character, or changing an existing mapping, could cause a variance between the behavior of systems that have been updated and systems that have not been updated.
