The PRECIS framework makes internationalised user names and passwords safer for use by applications.
PRECIS profiles transform unicode strings into a canonical form, suitable for comparison.

This module implements the PRECIS Framework as described in:
- PRECIS Framework: Preparation, Enforcement, and Comparison of Internationalised Strings in Application Protocols (RFC 8264).
- Preparation, Enforcement, and Comparison of Internationalised Strings Representing Usernames and Passwords (RFC 8265).
- Preparation, Enforcement, and Comparison of Internationalised Strings Representing Nicknames (RFC 8266).
