How to fix encoding in Facebook Pixel?

Question

Facebook

Installed this miracle on the site.
Website in utf-8.
I do so.

<script>
  var pageData = {
    "title": "<?=$pageData_title();?>", // Вывод заголовка
    "category": "<?=$pageData_category;?>" // Вывод категории
  }
</script>

Sending it all to facebook pixel

fbq('track', 'ViewContent', {
    content_name: pageData.title,
    content_category: pageData.category
  });

And I get that in facebook pixel writes everything in unicode.

Can you tell me how to fix this issue? Googled, tried some options, but so far without results.
