}
} else {
if ($thisValue < 128) {
$unicode [] = $str [$i];
} else {
if (count ($values) = = 0) {
$lookingFor = ($thisValue < 224)? 2:3;
}
$values [] = $thisValue;
if (count ($values) = = $lookingFor) {
$number = ($lookingFor = = 3)?
(($values [0]%) * 4096) + (($values [1]% *) + ($values [2]% 64):
(($values [0]%) * + ($values [1]% 64);
$number = Dechex ($number);
$unicode [] = (strlen ($number) ==3)? " \u0 ". $number:" \u ". $number;
$values = Array ();
$lookingFor = 1;
}//If
}//If
}
}//For
