The zero-width space (ZWSP) is a non-printing character used in computerized typesetting to indicate word boundaries to text processing systems when using scripts that do not use explicit spacing, or after characters (such as the slash) that are not followed by a visible space but after which there may nevertheless be a line break. Normally, it is not a visible separation, but it may expand in passages that are fully justified. In HTML pages, this space can be used as a potential line-break in long words as a replacement for the non-standard <wbr>
tag. However, the zero-width space is not supported in all web browsers, most notably Internet Explorer version 6 and below.
It is encoded at Unicode U+200B zero width space (HTML: ​
). To show the effect of a zero-width space, the following words have been separated with zero-width spaces:
