About Text Cleaner — Remove Hidden Characters

Scan and clean text from invisible and problematic Unicode characters. Detects zero-width spaces (ZWSP, ZWNJ, ZWJ, BOM), bidirectional control marks, non-breaking spaces, soft hyphens, smart quotes, em/en dashes, ellipsis characters, and variation selectors — each with a live count before you clean. Choose exactly what to fix: strip invisible format characters, convert NBSP to regular spaces, straighten curly quotes, collapse repeated spaces, trim trailing whitespace, and normalize Unicode (NFC/NFKC). Bidi mark removal is opt-in so legitimate RTL text is never silently destroyed. Includes a highlight mode that renders every hidden character as a visible placeholder. 100% client-side — your text never leaves the browser.
