The int codepoint value (e.g.
0x2603for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g."\u{2603}")
Return Values

Examples
Example #1 Testing different code points
<?php
var_dump(IntlChar::isUWhiteSpace("A"));
var_dump(IntlChar::isUWhiteSpace(" "));
var_dump(IntlChar::isUWhiteSpace("\n"));
var_dump(IntlChar::isUWhiteSpace("\t"));
var_dump(IntlChar::isUWhiteSpace("\u{00A0}"));
