codepoint has the Uppercase Unicode property, false if not. Returns null on failure.
Exemplo #1 Testando diferentes pontos de código
<?php
var_dump(IntlChar::isUUppercase("A"));
var_dump(IntlChar::isUUppercase("a"));
var_dump(IntlChar::isUUppercase("Φ"));
var_dump(IntlChar::isUUppercase("φ"));
var_dump(IntlChar::isUUppercase("1"));
?>

bool(true) bool(false) bool(true) bool(false) bool(false)
