Zero Width Space (U+200B) Unicode Character

What Is the Zero-Width Space (U+200B)?

The Zero-Width Space (U+200B) is a non-printing character used in computerized typesetting. It does not display a visible glyph and has exactly zero horizontal width. It is primarily used to suggest line break opportunities within long words, preventing text container overflows on narrow mobile screens.

How the Zero-Width Space is Used in Web Design

In web layouts, long URLs or words can overflow their parent containers, breaking mobile responsive grids. By placing a zero-width space inside a long string, the browser knows it can break the line at that point if necessary.

Example Implementation in HTML

<!-- Browser can break line between words if container is too narrow -->
<p>Supercalifragilistic&#8203;expialidocious</p>

Using U+200B ensures the text displays correctly without inserting visible hyphens or dashes.

Bypassing Form Validations and Chat Trimming

Because U+200B is a valid character, pasting it into a mandatory input field can bypass empty field checks. In messaging apps like WhatsApp, sending a zero-width space allows you to send an empty message bubble.
