Just tossing this out there, from the [`json_encode()` documentation page](https://secure.php.net/manual/en/function.json-encode.php): *"All string data must be UTF-8 encoded."* That being said, the `JSON_UNESCAPED_UNICODE` bitmask option sounds promising. — Spencer D, Nov 21 '16 at 06:42

Use the following code:

function utf8_converter($array) {
    array_walk_recursive($array, function(&$item, $key) {
        if (!mb_detect_encoding($item, 'utf-8', true)) {
            $item = utf8_encode($item);
        }
    });

    return $array;
}

$data = array("0"=>"hello","1"=>"180.00 10µH");
$data = utf8_converter($data);
echo json_encode($data, JSON_PARTIAL_OUTPUT_ON_ERROR);

Your code output: `["hello","180.00 10\u00b5H"]`. Notice the `µ` converted to respective special characters(`\u00b5`). – Bhavik Shah Nov 21 '16 at 06:41
@BhavikShah yes, right. It will do it. But whenever you are converting it back using json_decode it will come back to it's origin form. So don't worry about it. – Keyur Mistry Nov 21 '16 at 06:42

Try this:

$dat = array("0"=>"hello","1"=>"world");
echo json_encode($dat);   // work

$data = array("0"=>"hello","1"=>"180.00 10µH");
echo json_encode($data, JSON_UNESCAPED_UNICODE);
