• Remove hidden Unicode from text

  clean_text

  Return the text with invisible characters, bidi controls, tag characters and control characters removed and unusual spaces turned into normal spaces. By default ZWJ/ZWNJ/VS16 are kept inside emoji sequences, between letters of joining scripts (Arabic, Persian) and after an Indic virama (keep_joiners=true); strict=true removes them everywhere. Optional: map lookalike letters to Latin (lookalikes) and apply NFKC normalisation (nfkc). Read-only. Same engine as GET /api/clean.
