Platform rules at a glance
- Instagram: fancy fonts work in the name field, bio (150 characters) and captions, not the username.
- TikTok: name, bio (80 characters) and captions accept fancy fonts.
- X: most fancy characters count as 2 of your 280.
- Discord: display names, messages and server names; usernames are lowercase only.
- WhatsApp: built-in bold, italic and strikethrough plus Unicode fonts.
- LinkedIn: no bold button in posts, so Unicode bold fills the gap.
Fancy fonts and search
Apps search plain text. Put the words you want to be found for in plain letters and use fancy fonts for decoration.
