What is invisible text?
Invisible text — also called blank text, blank space or a Unicode empty character — is a real Unicode codepoint that occupies space but renders nothing visible. To people, it looks like nothing; to apps like Instagram, TikTok, Discord, WhatsApp, Telegram and Among Us, it counts as valid text. That makes it perfect for blank usernames, empty bios, invisible chat messages and clean line-breaks where the platform refuses an actual empty input.
