The problem is that U+00A0 has zero lccode and (Xe)TeX abandons hyphenation
whenever it finds such a character. So the solution would be to add

  \lccode"A0="A0

to you preamble. However, this is not a good solution, because this "space" will
not stretch or shrink together with the other interword spaces on the same line.
The explicit tie is way better. You can achieve the same behavior as ~ with

  \catcode`<NBS>=\active
  \protected\def<NBS>{\nobreakspace{}}

or, loading the new package newunicodechar,

  \newunicodechar{<NBS>}{\nobreakspace{}}

Here <NBS> denotes the character U+00A0, of course and that
character must be used.

Ciao
