     Type:  Bugs                       |      Status:  new      
Milestone:  Boost 1.42.0               |   Component:  iostreams
  Version:  Boost 1.39.0               |    Severity:  Problem

---------------------------------------+------------------------------------
 It appears aggreate_filter is incapable of handling character types other
 than char. When you for instance try using wchar_t, you'll get following
 compiler error:

 boost/iostreams/filter/aggregate.hpp(95): error C2664: 'void
 boost::iostreams::aggregate_filter<Ch,Alloc>::do_write<Sink>(Sink &,const
 char *,std::streamsize)' : cannot convert parameter 2 from 'wchar_t *' to
 'const char *'
         with
         [
             Ch= wchar_t,
             Alloc=std::allocator<wchar_t>,
 Sink=boost::iostreams::non_blocking_adapter<boost::iostreams::detail::linked_streamuf<
 wchar_t >>
         ]
         Types pointed to are unrelated; conversion requires
 reinterpret_cast, C-style cast or function-style cast.

 Patch attached.
