I saw this later on and this matched my implementation (but I did not know about dropping the 16):
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2035.pdf
but this doesn't work, even apparently with the microsoft compiler. something funny with the standard?
previous revision I thought this was the problem:
is this the reason? http://sourceforge.net/p/mingw-w64/mailman/message/31588691/
I have no idea how to make UNICODE work with std:
stringstream. eventually it needs to go to std::cout.
so: what is wrong in the first error? I don't understand why something is protected. somebody said something about
fstream containing the implementation of ostream in gcc (not sure if this is stil true). apparently, msvc++ has this problem too.
seems like something I ought to be able to do simply, but it just breaks. not sure why this is protected.
there is no wstring_convert. I grepped for it.

I was told to use a streambuf (since it's in the class as a contructor). however, when I DO use it, I get an error that it's protected.

apparently same problem with VC++ too, so wondering if it's a spec problem.
would prefer to typedef something if I can. if I could make changes to the class and submit a patch, I would, but not exactly sure of the details involved for char16_t on gcc.
