Unicode defines several other non-break space characters that differ from the regular space in width:
- No-break thin space, known in Unicode as “Narrow No-Break Space” (U+202F narrow no-break space (HTML:
 )). It was introduced in Unicode 3.0 for Mongolian, to separate a suffix from the word stem without indicating a word boundary. Also required for French punctuation (before ?, ! or ;). - Word joiner, encoded in Unicode 3.2 and above as U+2060 and HTML as ⁠. The word-joiner does not normally produce any space but prohibits a line break on either side of it.
- The Byte Order Mark, U+FEFF, officially named “Zero Width No-Break Space”, can also be used with the same meaning as the word joiner, but in current documents this use is deprecated. See also Zero-width non-breaking space.
