Enable Emoticons
Emoticons let your users add expressions like a smiley face to their posts and comments by typing a character combination.
Emoticons aren’t supported in the Salesforce app.
1. From Setup, enter Chatter Settings in the Quick Find box, then select Chatter Settings.
2. In the Emoticons in Feed section, select Allow Emoticons.
Salesforce supports these character combinations in posts and comments.
