ICANN rules prohibit domain names from containing non-displayed characters, including the zero-width space, and most browsers prohibit their use within domain names because they can be used to create a homograph attack, where a malicious URL is visually indistinguishable from a legitimate one. [3] [4]
The zero-width space character has a higher breaking priority than the hyphen character (-), so when using it in a phrase with hyphen, it is recommended to place a zero-width space immediately after each hyphen as well. There are two ways to use this template: With no arguments, i.e. {{zwsp}}, this produces a single zero-width space character
A second common application of non-breaking spaces is in plain text file formats such as SGML, HTML, TeX and LaTeX, whose rendering engines are programmed to treat sequences of whitespace characters (space, newline, tab, form feed, etc.) as if they were a single character (but this behavior can be overridden).
In links, spaces and underscores (_) are treated equivalently. Underscores are used in URLs, spaces in displayed titles. Leading and trailing spaces/underscores are stripped, consecutive spaces/underscores are reduced to a single one, and page names consisting of only spaces and underscores are not allowed at all.
Unicode's U+FEFF ZERO WIDTH NO-BREAK SPACE character can be inserted at the beginning of a Unicode text to signal its endianness: a program reading such a text and encountering 0xFFFE would then know that it should switch the byte order for all the following characters. Its block name in Unicode 1.0 was Special. [5]
This web page [dead link ] can be used to see how Unicode space characters display in a browser window. Example Gonzales added that "{{nnbsp}}'interesting times' is quite a euphemism for this chaos". → Gonzales added that " 'interesting times' is quite a euphemism for this chaos".
