Agree it would be cool if this site would enable modern emoji. The emoji wouldn't need to be represented necessarily when you open up the emoji window in the Pinside reply box, but it would be nice if it could display the emoji that you have access to in Windows 10 ("Windows + .") or on MacOS (I forget the shortcut).
FWIW: I'm a middle-aged man. My parents use emoji more than my teenager nephews.
