You're right, this is a problem. The reason is that the Unicode right- 
single-quote (or apostrophe) character U+2019 has not been given a non- 
zero \lccode, and therefore it is considered a nonletter by the  
hyphenation routine.

If you put


into your document, you should get the hyphenation you expect.

I'm not sure whether this should be built into the xe(la)tex format,  
controlled by babel or polyglossia depending on the language in use,  
or what.... suggestions are welcome.
