Unit test framework test tools require an output operation for the values 
being compared. That's why you are faced with this issue. Boost.Test is 
based on ostreams and there is no operator<< defined for wstring. You 
should be able to shutdown output completely for wstring using
BOOST_TEST_DONT_PRINT_LOG_VALUE macro.

Unfortunately complete support for wide string or even more generally for
unicode is not simple project and require significant time investment. I 
am not sure at this point when I'll get to it, even though it's on my 
todo list.
