Yes, the crucial part is providing a toString from wstring to string.
While converting to UTF-8 may make sense in your use case, that need not
generally hold. Also, codecvt_utf8 is only available since C++11. So a
more generic solution might be to use the default
codecvt<wchar_t,char,mbstate_t>. Also, the convenience class
wstring_convert is only available since C++11.
