A zero-width space (ZWSP) is a Unicode character that represents an invisible breaking space used to indicate a potential separation of a word.
The space without hunting has the particularity of leaving no visible trace.
Non-width spaces are encoded with the unicode character U+200B which can be inserted into text using a special keyboard shortcut or by copying and pasting the appropriate Unicode character (not visible).
The HTML standard provides the following HTML entities for inserting a zero-width space: &zwsp; or ​. Unicode codes also work or .
Example: The ZWSP message contains a blank space between ZW and SP
There are 4 non-width characters in Unicode
— U+200B zero width space
— U+200C zero width non-joiner
— U+200D zero width joiner
— U+FEFF zero width no-break space
dCode detects them identically.
Messages containing ZWSP spaces (or other non-width characters) are visually identical to regular messages. Only a dedicated application will be able to display non-width characters which by definition are invisible by default.
