How zalgo text works
Zalgo is a 2000s internet meme — a creeping horror that corrupts text. Technically it is just letters followed by dozens of combining diacritics from the U+0300 to U+036F block. Unicode lets any number of them attach to a single letter, and the text renderer dutifully stacks them.
Pick where the marks go: up, through the middle, or down. Choose a new seed for a different pattern of marks, then copy.

Questions
Why is it called Zalgo?
The name comes from a 2004 Something Awful forum meme where comic strips were edited to feature a creepy entity called Zalgo. The warped text style came with it.
How many marks can one letter have?
Unicode sets no limit, but the Unicode “Stream-Safe Text Format” recommends at most 30 in a row, and most apps cut far earlier.
Can Zalgo text crash an app?
Modern apps handle it, but very long runs can slow rendering. That is why many platforms strip or limit combining marks.
