♥, ★, ► in estimates PDFs - Customers LOVE it!

To enrich the estimates, we used symbols (♥  ★  ► ☆ ... ) in the articels, like shown below.
Our customers love it ♥
The estimates are more appealing for the decisionmaker:

☆ Branding: the company logo is visible on the display and therefore on all photos and videos. ➽ The Robot can shake hands, hug, fist-bump and high-five in one smooth motion.
★ ★ ★ ★ ★ "Using the Robot at our convention was a huge success! He was the good mood ambassador, everyone wanted to try him. Thank you very much for the good cooperation." Association of Consulting Engineers Germany ___________________

They are shown in the online estimate, BUT: When converting to PDF, they disappear...
I attached the screenshots.

How to solve that? Zoho uses the OpenPDF Version 1.3.26.
The newest version is 1.3.30. Does Zoho only need to update their OpenPDF integration?
Or is their another solution for us?

Thank you for your help!
