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::do_write(Sink &,const char *,std::streamsize)' : cannot convert parameter 2 from 'wchar_t *' to 'const char *' with [ Ch= wchar_t, Alloc=std::allocator, Sink=boost::iostreams::non_blocking_adapter> ] Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast. Patch attached." Bugs closed Boost 1.42.0 iostreams Boost 1.39.0 Problem fixed
