The Unicode Consortium seems very confused over this, probably because 
of the format they've chosen for the character info tables they publish, 
which they don't want to change now because software relies on it (the 
only way of specifying an alternate name seems to be to deprecate the 
old name to the "1.0 name" field, and use the new name as the preferred 
name). It was renamed to ZWNBSP in Unicode 2.0 to reflect its dual 
purpose as BOM and zero width no break space.  Then in a later version 
of Unicode its use as ZWNBSP was deprecated, but the official name was 
not changed back (swapping the ZWNBSP and BOM names would not be 
strictly correct, as ZWNBSP was not its name in Unicode 1.0).
