What browser and operating system are you using? Did you try re-downloading this particular PDF to ensure it's not corrupted in any way?
Zen Browser is based on Firefox, so it should work, and in fact, it does work for me on macOS (see below). I suspect this might be related to the fonts on your system or something specific to Zen Browser on Windows. I'd recommend trying one of the mainstream browsers (Chrome/Firefox/Edge) to confirm.
