[name_m]Hi[/name_m] @regionlatbest,
Bold and italics don’t display anyway on the user cards, as far as I know, but emojis should 
When I click through to your profile, I can see a grey box around your profile information. What exactly are you typing in there, including any punctuation marks, etc.? It looks like you might have accidentally used some Markdown which is causing some unexpected formatting.
ETA: [name_m]Ah[/name_m] yes, I see. It’s the indent you’ve used. The indent is causing your profile info to be rendered like code. If you remove the indent and just left-align and type like a normal post, all your emojis should work fine on both user card and profile page, and any bold and italic formatting will display on your profile page only.
