Hi there!
Half seriously, half fun, but sometimes I use emojis to describe stuff.
It would be great to preview them in the panel too.
As we see here:
On left: We can preview emoji via rhinocommon conduit.
On right: We can’t see the emoji preview in the GH panel.
Interestingly, the emoji preview does exist while editing the panel 
Verified on Windows Rhino 7 and Rhino Beta, but it seems like it’s the same 1.0.0007 version from 12.09.2023. And I have tried some other panel fonts to make sure it’s not the reason.
Cheers!
