Hi ThosEnt to fix this problem
in [website]/wp-content/plugins/mage-reviews/core/mage-cast.php
replace
$string = preg_replace('/[^A-Za-z0-9_-\s]/', '', $string);

with
$string = preg_replace('/^([-\w\s])+$/i', '', $string);

Hi Nick ,
if you want to fix Hebrew words/phrases reversed problem in PDF you can use this code in this file
woocommerce-pdf-invoices-packing-slips/lib/dompdf/include/text_renderer.cls.php

before this line
$this->_canvas->text($x, $y, $text

add this code

if (strtolower($style->direction) == 'rtl' && !mb_detect_encoding($text, array("ASCII"))) {
  preg_match_all('/./us', $text, $ar);
  $text = join('',array_reverse($ar[0]));
  // if there are numbers in the string
  // so the next line reverse the number back
  // treat also numbers with dot (decimal) and email
  $text = preg_replace_callback('/\d+-\d+|\d+|\d+\.\d+|\S+@\S+/', function (array $m) { return strrev($m[0]); }, $text);

}

this will fix reversed letters
