Adding unicode chars to memes?

[albacoretuna]

Currently Unicode chars are not supported for example this:

Doesn't render the check mark.

Is there a work around?

Thanks for this! It's awesome.

I'm guessing this is because the Impact font file that I'm using does not include glyphs for emojis? Not sure.
