To convert wide strings to char or multi-byte without loss of information, the wide string must only contain characters from a specific known character set / code page.

When using the wcstombs() conversion function, you must first set the locale to those used by the input string and restore it after conversion (see setlocale()[^]). The default locale is 'C' which is not language specific (English).

Another method is using WideCharToMultiByte()[^] where the code page can be specified:
int nCP = 1252; // Example: Windows-1252
// Get required buffer size
int nSize = ::WideCharToMultiByte(nCP, 0, str.GetString(), -1, NULL, 0, NULL, NULL);
char *nstringw = new char[nSize];
::WideCharToMultiByte(nCP, 0, str.GetString(), -1, nstringw, nSize, NULL, NULL);

If the code page of the input string is the same as for the current thread, you can use conversions provided by the CStringT class. This should do the job in most cases:
// Create a char/multi-byte string from wide string.
// Pass LPCSTR to constructor, so use casting or GetString()!
CStringA strA(str.GetString());
// Convert it back to a wide string
CStringW strW(strA.GetString());
