Because XPath <http://w3.org/TR/xpath#function-normalize-space> says:

  Whitespace characters are the same as those allowed by the S production in
XML

And XML <http://www.w3.org/TR/REC-xml/#NT-S> says:

  [3]   	S	   ::=   	(#x20 | #x9 | #xD | #xA)+

thus NO-BREAK SPACE is not whitespace.

Cheers,
