Allow implementation-defined Unicode version, but require at least version 15.1.
Possible resolution [SUPERSEDED]:
Change in Clause 2 [intro.refs] paragraph 1.10 as follows:
Add a paragraph before 4.1.1 [intro.compliance.general] paragraph 8 as follows:
A conforming implementation may implement an implementation-defined version of the Unicode Standard that is a later version than the one referenced in Clause 2 [intro.refs].
A conforming implementation may have extensions (including additional library functions), provided they do not alter the behavior of any well-formed program.
