SchemaMetatagManager::encodeJsonld Should Allow for HTML

Problem/Motivation

SchemaMetatagManager::encodeJsonld uses json_encode() with a number of options that garble any HTML contained in $items. This is problematic in the case of job postings because Google requires the 'description' property to be valid HTML: https://developers.google.com/search/docs/data-types/job-posting#JobPost....

Specifically, the json_encode() options are as follows:

• JSON_HEX_TAG
• JSON_HEX_APOS
• JSON_HEX_AMP
• JSON_HEX_QUOT

Proposed resolution

Remove the options in question:

  public static function encodeJsonld(array $items) {
    // If some group has been found, render the JSON LD,
    // otherwise return nothing.
    if (!empty($items)) {
-     return json_encode($items, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES | JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_AMP | JSON_HEX_QUOT | JSON_UNESCAPED_UNICODE);
+     return json_encode($items, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
    }
    else {
      return '';
    }
  }
