TRUE
for more characters.

返回值

if not.
范例
Testing different code points
<?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")); ?>
以上例程会输出:
bool(true) bool(false) bool(true) bool(false) bool(false)
