[Evolution] Emojis/icons in subject line

I used to get pictures of icons/emojis in the subject lines of certain
emails, but now all I'm getting are weird boxes with numbers in them.
Here's an example:

📦 (this is displaying as an outlined box with '0 1 F' on the top line, '4
E 6' on the bottom)

Is this part of a font that I may not have? I recently switched all of my
default fonts to Bitstream Vera Sans/Mono, removed all of the Noto fonts.
I checked this symbol with Character Map, and it's showing this box as
part of the Common script.
