> Name Uniqueness
Applicable Version: Unicode 2.0+
The names of characters, formal aliases, and named character sequences are unique within a shared namespace.
The names of characters, named character sequences, and formal aliases for characters share a single namespace in which each name uniquely identifies either a single character or a single named character sequence. The definition of uniqueness is not just a simple comparison of the characters—instead, the loose matching rules from UAX #44, Unicode Character Database are used.
