How are invisible Unicode characters removed?
The cleaner removes unnecessary hidden and control characters according to context. It preserves needed joining characters and recognized emoji sequences. Ambiguous characters appear in the report for review.
Will it preserve my language and emoji?
The default Keep language mode preserves Unicode letters, including Ukrainian, Japanese and Korean, and applies NFC normalization. Needed language and emoji controls are preserved. Review any flagged characters before using the result.
What changes in ASCII only mode?
The original text is audited first, including suspicious ASCII lookalikes. Cyrillic is transliterated and accents are removed. Unsupported characters, including emoji and many non-Latin letters, become ?. Conversion losses are reported.
Is my text uploaded to a server?
No. Text processing runs on your device in the browser. No account or text upload is required. The downloadable CLI also processes text locally and works offline.
