In (Xe)LaTeX, \, inserts a kern and TeX won't break a line at a kern unless
it's followed by glue (a normal space, usually). Thus you can get what you
want by

\newunicodechar{<U+2009>}{\,\hspace{0pt}}
\newunicodechar{<U+202F>}{\,}

(with the real characters, of course). The newunicodechar package was
designed primarily in order to free the user from the need to consult long
code pages. Maybe I'll add the possibility to specify a character by code
point (in XeLaTeX, as with LaTeX there's already \DeclareUnicodeCharacter).

Ciao
Enrico
