What are invisible characters and zero-width spaces?
Invisible characters, like the zero-width space (ZWSP, U+200B), non-breaking spaces, or soft hyphens, are unicode characters that occupy no visible layout space on your screen. However, they remain embedded inside your clipboard strings, causing unexpected compilation errors in code scripts or breaking database search query structures.
