Why an "empty" character is useful

A zero-width space (U+200B) is a real character that renders as nothing. Forms and platforms that block empty inputs usually check for length or visible characters - an invisible character passes those checks. People use them for blank-looking usernames, empty lines in bios that platforms strip, and line-break hints in long words.

Honest limits: some platforms specifically strip zero-width characters (Discord, X have done so at times), and invisible characters in real prose break search and screen readers. For ordinary empty-looking messages, a single no-break space (U+00A0) is often the most compatible choice.
