Question 1

What is invisible text?

Accepted Answer

Invisible text is made of Unicode characters that appear blank — like Hangul Filler (U+3164) or Zero-Width Space (U+200B). They look empty but take up space, useful for blank messages.

Question 2

What's the difference between Hangul filler and zero-width?

Accepted Answer

Hangul filler (U+3164) renders as a visible blank space in most apps. Zero-width space (U+200B) is truly invisible — it takes no visual space but still counts as a character.

Question 3

Will this work on WhatsApp?

Accepted Answer

Yes! Copy the invisible text and paste it into any WhatsApp chat. Some apps may trim very long blank messages.
