The zero-width space is an invisible character that marks a potential line-break point without displaying anything at all — shown here with the placeholder ∅. It is a frequent source of hidden-character bugs.
Legitimately used to allow line breaks inside long unbroken strings. Also abused for invisible watermarking and to defeat text filters. Detect and remove it with our invisible character detector.
