Closed-eye smile copy & paste

(⌒‿⌒) is closed-eye smile, a plain-text Unicode symbol built from several characters from the Basic Latin and Miscellaneous Technical and General Punctuation blocks. On Aesthetic Symbols it lives in the kaomoji & emoticons collection. As plain text it takes on the font and colour of wherever you paste it — a bio, a username, a caption or a stream title.
