The zero-width space (), abbreviated ZWSP, is a non-printing character used in computerized typesetting to indicate where the word boundaries are, without actually displaying a visible space in the rendered text. This enables text-processing systems for scripts that do not use explicit spacing to recognize where word boundaries are for the purpose of handling line breaks appropriately.
The zero-width space is Unicode character U+200B
, and is located in the Unicode General Punctuation block. In HTML, it can be represented by the character entity reference ​
