Writing wide character streambufs is currently a pain in the neck - it should be unnecessary in most cases. See http://www.dinkumware.com/manuals/reader.aspx?b=cx/&h=wbuffer.html It could be generalised further to convert between arbitrary character types I think... Currently you have to do, e.g. template <class CharT, class Traits> class MyStreambuf: public basic_streambuf<CharT, Traits> { //scary implementation using codecvt? }; whereas it would be much simpler to do: class MyStreambuf: public std::streambuf { //simple implementation for char }; //code conversion hidden in wbuffer_convert typedef codecvt<wchar_t, char, mbstate_t> cvt; typedef wbuffer_convert<cvt> wbuf; wbuf myBuf(new MyStreambuf); Obviously some cooperation from Dinkumware might be necessary or at least helpful...

We have no problem with wbuffer_convert being proposed for standardization, but we're in no hurry to propose that ourselves. We prefer the old fashioned approach of getting experience, and refining design based on user feedback, before foisting a feature on all implementations. P.J.
