WString support?

[imtrobin]

Hi, when I try to use a wstring in add_property, I get a compile error

staticjson_init': is not a member of 'std::basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t>>

You can write your custom converters. I do not officially support it because it is only useful on Windows, and no portable way to convert it from/to std::string.
