Thanks guys! Now it is working fine on Linux (with LANG=en_US.utf8 at  
least). I put my utf8_facet inside a shared_ptr that lives throught  
my app so thats solved.
However, on OS X it still wont work, not sure why.. When I do  
fs::wpath_traits::imbue( loc ); I get an  
"locale::facet::_S_create_c_locale name not valid" exception.
I'm running with LANG=en_US.UTF-8 here, which (according to locale in  
console) is fine.

Any clues?

Thanks
