Remove invisible characters
Strips zero-width spaces, bidi overrides, tag characters, variation selectors, private-use and noncharacters — and names every codepoint it removed.
Tools
Unicode text tools
Each tool is disarm itself, compiled to WebAssembly and run inside your browser. No text is uploaded, and every one of them reports precisely what it changed — because on hostile Unicode the before and after usually look identical.
Available tools
Detect Trojan Source
Finds the bidirectional controls that make source render differently from how it compiles, with line and column for each — and flags the direction conflict that stripping them cannot fix.
Check confusable characters
Fold TR39 confusables and flag whole-script spoofs — the case a mixed-script check alone cannot catch.
