Twitter Logo
The logo for Twitter is a Private Use Area (PUA) character that is supported on the Twitter website and apps, as of August 2021. Inserting this character displays a silhouette of Twitter's bird logo.
Typing [CHIRPBIRDICON] also displays this logo within text on the Twitter website, without using a distinct PUA code point.
Like the Apple logo, this character is not recommended for interchange as it is only intended for support on Twitter platforms.
