IntlChar::charAge — Get the "age" of the code point
$codepoint): ?arrayGets the "age" of the code point.
The "age" is the Unicode version when the code point was first designated (as a non-character or for Private Use) or assigned a character. This can be useful to avoid emitting code points to receiving processes that do not accept newer characters.

For example, version 1.3.31.2 would be represented as [1, 3, 31, 2].
