UTS #39: Unicode Security Mechanisms

Unicode Technical Standard #39 provides mechanisms to detect security vulnerabilities that arise from the large number of Unicode characters and diverse writing systems, which could be exploited if used incorrectly in programs or systems. The standard specifies detection methods for identifier security, confusable character detection, and mixed-script usage to help prevent potential security attacks. This stable, Unicode Consortium-approved document serves as a reference for developers implementing security measures in Unicode-based applications.
