Could you Igor tell me what is the difference between
your string specialized by TCHAR and std::wstring
which AFAIK is specialized by wchar_t.
TCHAR is a typedefed this way:

typedef wchar_t TCHAR;

No it's not, it depends on _UNICODE (or UNICODE, I forgot):

#ifdef _UNICODE
typedef wchar_t TCHAR;
#else
typedef char TCHAR;
#entdif

This schema runs through the whole win32 API, where you have functions like
CreateFile( TCHAR const* filename, ...)
which in truth comes in two varieties:
CreateFileA( CHAR const* filename, ...)
CreateFileW( WCHAR const* filename, ...)
#ifdef _UNICODE
# define CreateFile CreateFileW
#else
# define CreateFile CreateFileA
#entdif
