IntlChar::isUUppercase — Check if code point has the Uppercase Unicode property

Açıklama

public static IntlChar::isUUppercase(int|string $codepoint): ?bool

Check if a code point has the Uppercase Unicode property.

This is different than IntlChar::isupper() and will return true for more characters.

Bağımsız Değişkenler
