RFC 3454: Preparation of Internationalized Strings ("stringprep")

This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 7564.

Current document in this lineage: RFC 8264 — PRECIS Framework: Preparation, Enforcement, and Comparison of Internationalized Strings in Application Protocols

In plain English — editorial summary, not part of the RFC

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. [STANDARDS-TRACK]
