Unicode and ofstream -- dotnet internationalization

dotnet internationalization : Unicode and ofstream

Hi,

I have a very simple program below. I am trying to output Unicode characters
in a file.

-----------

ofstream logFile("myLog.txt");
logFile << L"ABC"; // In the actual scenario, the characters will
include multinational characters.

---------

After the program is run, the myLog.txt includes:

004980DC

Is there a Unicode counterpart of ofstream? Or do I need to somehow convert
the numbers above to actual characters?

By the way, MFC cannot be used in my environment.

Thanks much,
TomTom

use wofstream and read

P.S. and don't forget the BOM (byte order mark) - mentioned in one of the
comments in the codeproject article.

Thanks, Ted. I could make it work for Western European characters such as
"ABC", but I see nothing for the non-European chars, such as Japanese. I
saved the NotePad as Unicode, but then I see garbage instead of the Japanese
chars.

The code looks like this.

void WriteToLog(BSTR myText)
{
wstring convertedText = wstring(uiText, lstrlen(myText));
char logFileName[] = "myLog.txt";
wofstream logFile(logFileName, ios::app);
logFile << convertedText.c_str() << L"\n";
logFile.close();

}

To get it to work with those characters, you must use binary and follow the
advice in the links that I gave you (e.g. write BOM)

wofstream fout;
fout.imbue( locale(locale::classic(), new NullCodecvt) );
fout.open(sPath.c_str(), ios::out|ios::binary);
fout << wchar_t(0xFEFF);

Great.. Now there is no text corruption.

Thank you!
