Frequently asked questions

How do I detect invisible characters in text?

Paste the text into the box above. The tool lists every character with its Unicode code point and highlights invisible or unusual characters.

What are zero-width spaces?

Zero-width space (U+200B) and zero-width non-joiner (U+200C) are invisible characters sometimes hidden in copied text. This tool reveals them so you can remove them.

Is my text uploaded?

No. Inspection happens entirely in your browser. Your text never leaves your device.
