A byte-order mark (U+FEFF) — an invisible character some editors add at the start of files. It breaks PHP headers, JSON parsing and CSV imports.
Zero-width spaces (U+200B), joiners (U+200C/D) and word joiners (U+2060) — all common copy-paste contaminants.
A BOM at the file start outputs bytes before your code runs — removing it fixes the error.
No. Cleaning runs entirely in your browser.
