Zalgo text stacks multiple Unicode combining marks above, below, and through each letter, producing the chaotic, 'corrupted' look associated with creepypasta and glitch aesthetics.
Each character in your input gets a random number of combining diacritical marks attached to it, pulled from Unicode ranges normally used for accents in other languages. Stacking several at once is what creates the glitchy, distorted appearance rather than a clean accent.
Because each letter can carry many stacked marks, Zalgo text takes up far more data than it appears to visually — some platforms with strict character or byte limits may cut it off or reject it entirely.
Popular for horror-themed usernames, creepypasta-style posts, and general glitch aesthetics in captions and comments.
No — the marks are chosen randomly each time, so regenerating the same input produces a slightly different, equally glitchy result.
Some platforms cap the number of characters (including invisible combining marks) allowed in a field, and heavily stacked Zalgo text can exceed that limit even though it looks short.
No — it's just Unicode characters, the same as any other text on this site. The 'corrupted' look is purely visual.
