Since Char16.h is included everywhere, and MSVC 2015 uses the char16ptr_t trick it contains, we include <string> everywhere, but that has the side effect of breaking the build in subtle ways. One way around this would be to avoid including Char16.h in the first place, but that requires more work than I was ready to put in. So instead, just avoid including <string> by removing the conversion operator for std::wstring.
