Plus “+” signs in the download file link text

At the moment i’ve temporary fixed this by adding js code

But there must be more elegant way to fix this problem

jQuery(document).ready(function($) {

  setTimeout(function () {
    document.addEventListener('wpcf7mailsent', function (event) {
      setTimeout(function () {
        if ($('.download-lnk-pdf').length) {
          var pdfText = $('.download-lnk-pdf').text().replace(new RegExp('\\+', 'g'), ' ')
          $('.download-lnk-pdf').text(pdfText)
        }
      }, 300)
    }, false);
  }, 0)

})

I’ve fixed this by editing source code in the file wp-content/plugins/generate-pdf-using-contact-form-7/assets/js/cf7-pdf-generation-public.js

var pdf_download_link_txt_new = pdf_download_link_txt.replace(new RegExp('\\+', 'g'), ' ');

I’ve added new variable where i deleting all “+” signs. Somehow this string saves in cookies with plus signs.
