Summon cursed, dripping text. Type, copy, paste.
Zalgo text covers your letters in stacked combining marks for that cursed, creepy, glitch-horror look popular in usernames and edgy posts.
It is Unicode, so it pastes as text, but some platforms reduce the stacking. That is normal.
Type your text, copy the zalgo style, and paste it.
Text buried in stacked Unicode combining marks so it looks corrupted or cursed.
Some apps limit combining marks for safety, which trims the effect.
