Does it mean #codePoint: is a low level (basic) creation message,
private and not to be used except in special circumstances like
creating the CharacterTable, while #value is the public API?

Or does it mean any code using the ANSI protocol #codePoint: wont'
share the uniqueness property of #value:?

The category and comment made me think it was the latter, thus my question.
