Comment:

 problem here isn't that locale is ignored
 problem that method os.fill that tries to use facet before imbue to the
 stream
 see actor for the stream_format_state

         if(width_ != -1)
             os.width(width_);
         if(precision_ != -1)
             os.precision(precision_);
         if(fill_ != 0)
             os.fill(fill_);
         os.flags(flags_);
         os.clear(rdstate_);
         os.exceptions(exceptions_);
 #if !defined(BOOST_NO_STD_LOCALE)
         if(loc_)
             os.imbue(loc_.get());
         else if(loc_default)
             os.imbue(*loc_default);
 #else
         (void) loc_default; // keep compiler quiet if we don't support
 locales
 #endif

 imbue should be at very beginning of the actor, not at the very end
