Glitch text generator

Stacks combining marks above, through and below each character. Turn the intensity up and the text bleeds into the lines around it — the effect usually called zalgo.

Combining marks were designed so that any accent could be attached to any letter without encoding every combination separately. Nothing in the standard limits how many you can stack, and text rendering engines generally draw them all, which is where the effect comes from. Two consequences: the text becomes very long in codepoints, so it eats character limits fast, and it genuinely overflows its line box in most layouts, which is why some platforms strip it and why posting a lot of it is treated as abusive on several of them. Keep the intensity low for something you actually intend to post.
