convert unicode to char

Question

How can I convert a Unicode string to a char* or char* const in embarcadero c++ ?

Answer 1

If you work with Windows:

//#include 
u16string utext = u"объява";
char text[0x100];
WideCharToMultiByte(CP_UTF8,NULL,(const wchar_t*)(utext.c_str()),-1,text,-1,NULL,NULL);
cout << text;

We can't use std::wstring_convert, wherefore is not available in MinGW 4.9.2.
