Encode text as supported zero-width Unicode characters or decode an invisible sequence for controlled Unicode experiments. Not encryption.
Encode text into zero-width Unicode characters or decode a supported invisible-character sequence for Unicode experiments. Invisible Character Generator demonstrates how zero-width characters can carry encoded bits while appearing blank. It is useful for Unicode research and controlled testing, but invisible characters are not encryption and may be stripped by other software. How to use Invisible Character Generator: Enter a visible message. Encode it into zero-width characters or paste a supported encoded sequence for decoding. Copy the result and test it in the exact application where it will be used. Common uses: Unicode and text-rendering experiments Testing normalization behavior Controlled zero-width character demonstrations Are invisible characters secure? No. They are not encryption and should not be used to protect confidential information. Why might the output disappear? Apps, databases and text editors may normalize or remove zero-width characters. Can I decode the generated output? Yes. Use the decode action with a supported sequence.
