I would try using htmlspecialchars().

On the other hand if I was doing this I would probably built and array in PHP and then json_encode that array for output allowing PHP to deal with special characters.

<?php 
  if ($faq) {
    $ld = array(
      '@context' => 'https://schema.org',
      '@type' => 'FAQPage',
      'mainEntity' => array()
    );
    if (have_rows('faq')) {
      while (have_rows('faq')) {
        the_row();
        $ld['mainEntity'][] = array(
          '@type' => 'Question',
          'name' => get_sub_field('question'),
          'acceptedAnswer' => array(
            '@type' => 'Answer',
            'text' => get_sub_field('answer')
          )
        );
      }
    }
    ?>
      <script type="application/ld+json"><?php echo json_encode($ld); ?></script>
    <?php 
  }
?>
