Saving unicode strings to .txt files ..

Hi ..

In my project , we need to create an Array of Unicode Strings . The Array will contain 5000 Strings.

I need to write those strings to a text file which can be opened or edited with NotePad.

Normal _tfopen and fwrite are not able to create notepad compatible .txt file .. I mean the file I created is not

readable with Notepad though file open mode is "w+t"

How can I save my unicode strings to a text file

You can use CStdioFile Class
or Win32 API functions CreateFile + WriteFile
Also consider inserting BOM in the beginning of the file.

Like Victor already did, I also suggest to use CStdioFile MFC class, that can make your life easier.
However, if really-really need using CRT functions and no MFC...

Notepad, as well as other text viewers/editors, uses BOM (byte order mark) to get the file text encoding.
You can write it yourself or, better add ccs flag to fopen/_wfopen.

Example

Code:

---

    wchar_t* wchText = L"Ala bala portocala";
    FILE* f = _wfopen(L"c:\\test\\mytest.txt", L"w+t,ccs=UNICODE");
    if(NULL != f)
    {
        size_t size = fwrite(wchText, sizeof(wchar_t), wcslen(wchText), f);
        // ...
        fclose(f);
    }

---

For more details, see Remarks under fopen, _wfopen MSDN topic.

CStdioFile is a bad idea if you need to create a file with UNICODE contents because it will always enforce ansi-mode. You could find yourself in a situation working around MFC more than working with MFC.

either use CFile and do your own buffering and wide-string IO.
or use _wfopen as Ovidu suggests

... or use some extensions of CStdioFile like

I found this issue has been resolved in VS2012.
CFile::OpenFlags enum contains a new value, typeUnicode. So, to save unicode, you can do the following:

Code:

---

    // ...
    UINT nOpenFlags = CFile::modeCreate | CFile::modeWrite;
#ifdef _UNICODE
    nOpenFlags |= CFile::typeUnicode;
#endif

    CStdioFile file(_T("d:\\test\\mytest.txt"), nOpenFlags);
    file.WriteString(_T("Ala bala portocala\r\n"));
    // ...

Thanks thanks thanks to all of you ..

This site has supported me many times ..

I will read every thing carefully and will write down the program.
