    IntlChar::isUUppercase

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

    Description

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

    Check if a code point has the Uppercase Unicode property.

    This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_UPPERCASE)

    Note:

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