How zalgo text (heavy) works
This style does not replace your letters. After each character it inserts a combining mark from the Combining Diacritical Marks block (U+0300–U+036F). Combining marks are designed to sit on top of, through or under the preceding character, which is how accents like é are built. Stacking the right mark on every letter produces the effect.
Coverage for this style: Everything. Anything outside that range passes through unchanged.
