      if (plainText === origContent && !content.match(htmlRegex)) {
        hasContent = false;
      }

      content = escapeSync(cleanedString);
      hasContent = true;
    }

      hasContent = true;
      messageObject.mentions = {
        items: mentions
      };
      content = mentionsText;
      plainText = mentionsPlainText;
    }
