I think we can use `Character.isWhitespace`. For the most part it aligns with "is this a breaking space".  It's not perfect, but we can do more when there are complaints.  Here's my test:


char     isWhiteSpace (breaking space)?
\u0009   true
\u0020   true
\u00a0   false
\u1680   true
\u180e   false <- unexpected
\u2001   true
\u2002   true
\u2003   true
\u2004   true
\u2005   true
\u2006   true
\u2007   false
\u2008   true
\u2009   true
\u200a   true
\u200b   false <- unexpected
\u200c   false <- unexpected
\u200d   false <- unexpected
\u202f   false
\u205f   true
\u3000   true
