> The most correct C++ type for UTF-16 data is {{std::u16string}}, but due to a known bug in [MSVC|https://connect.microsoft.com/VisualStudio/Feedback/Details/1403302], the {{std::codecvt_utf8_utf16}} converter cannot be used with {{char16_t / u16string}} types, so we must use {{wchar_t / wstring}} types for now.

> I am deeply sorry for the statement I made about the availability of this fix. This is not fixed in Visual Studio 2017.
> This issue requires a binary breaking change to the VC++ libraries, so we cannot ship this fix in an update to the libraries. Visual Studio 2017 shipped with v141 of the libraries, which is a minor update and binary compatible with v140 (the version shipped with Visual Studio 2015).
> This bug will be fixed in the next major version of the Visual C++ Libraries.
> Thanks,
