Zalgo: Text

The term "Zalgo" refers to an internet-legend entity associated with cosmic horror, chaos, and the destruction of reality.

Ironically, it’s also used for comedic effect. Examples: zalgo text

Zalgo text appears in stories like Slenderman , Jeff the Killer , and The Russian Sleep Experiment — usually when a character becomes possessed or an otherworldly entity speaks. Take the letter A (U+0041)

Take the letter A (U+0041). Add combining tilde ◌̃ (U+0303) → Ã Add combining double acute ◌̋ (U+030B) → A̋̃ Add combining vertical tilde ◌̾ (U+033E) → A̾̋̃ Add more… and the text starts "leaking" up and down.

: It is not a unique font but a manipulation of Unicode's combining diacritical marks. These marks are designed to be placed above, below, or through base characters (like accents), but Zalgo generators stack them to an unintended and nearly limitless extent .

Zalgo text stacks many of these combining marks — sometimes 10–20 per base character — from different ranges (above, below, and through the letter). This overloading pushes the rendering engine past normal bounds, causing overlapping, vertical stretching, and chaos.
