API V2 not displaying Emojis

I recently added emoji support to my web app,
and now my customers are complaining that Emojis are displaying on the page,
but not in the .pdf exports...
So I upgraded to the new V2 API just in case that might fix it, but it's not working...

They either display as broken squares or text-based emojis...

Can you help me figure out what to do to support emojis in .pdfs
and then add it to your API documentation?
