I often see in Posts, together with regular text, Emojis added ( https://unicode.org/emoji/charts/full-emoji-list.html ) How can one do it ? For example, say that I wanted to add a smiling face at the end of this line, I would need to use the Unicode for # 9 at the link above which would be " U+1F642 ". But how do I do it ? I tried with keeping ALT pressed and then typing that code but it did not work. So, how to ? Thanks !
