Not bad

While creating an invoice for a new order and with debugging enabled I was receiving the following error:

count(): Argument #1 ($var) must be of type Countable|array, string given in /var/www/html/wp-content/plugins/woocommerce-pdf-invoices/vendor/mpdf/mpdf/classes/ttfontsuni.php, line 613

Changing line 613 from

for ($i = 0; $i < count($psName); $i++) {

to

for ($i = 0; $i < strlen($psName); $i++) {

seems to have fixed the problem.
