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.
