Its more complicated than that. It was previously renamed, then in a
later version of the Unicode spec, its use as a ZERO WIDTH NO-BREAK
SPACE character was deprecated as WORD JOINER, ZERO WIDTH JOINER and
ZERO WIDTH NON-JOINER provide the same functionality with more
detailed meaning, so it retains only the BOM usage, with the ZWNBSP
name.  Welcome to design by committee!
