IntlChar::charAge — Get the "age" of the code point
Beschreibung
public static IntlChar::charAge(int|string
$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.
