ofstream in UNICODE

I am porting some code to UNICODE.

The compiler doesn't like:

CString xxx;
ofstream fileOutput(xxx);

with error:

'__thiscall ofstream::ofstream(const char *,int,int)' : cannot convert parameter 1 from 'class CString' to 'const char *'

The code is fine in non-UNICODE.

Any ideas?

'ofstream' has no UNICODE-aware constructor, so attempting to use it with UNICODE strings is futile. Even

ofstream fileOutput( ( LPCTSTR) xxx);

will cause problems.

Use 'CFile' instead...

I thought there was a push for people to use the standard C++ language? Are there many other parts of it non-UNICODE compatible?

>>Are there many other parts of it non-UNICODE compatible?

Well, there are several (though I can't name them, as I only keep in mind the compatible ones ;-)

But as UNICODE support for the 'mainstream' OSs is limited to NT nowadays, I tend to use the Win32 UNICODE APIs when I have to deal with that character set...
