Question

How to write unicode to a file using MFC. I tried writing to a file using Cfile class but not sure on how to specify length of TCHAR also having trouble printing out new lines. A code snippet is welcome.

If you want an automatic conversion of \n to \r\n characters use CStdioFile and the methods ReadString/WriteString. Following example uses CFile:

CString strFileContent;
CString strFilePath; 

CFile theFile(strFilePath, CFile::modeReadWrite | CFile::modeCreate);

// write BOM if you like
// WCHAR bom = 0xFEFF;
// theFile.Write(&bom, 2);

theFile.Write( (LPCTSTR) strFileContent, 
    strFileContent.GetLength() * sizeof(TCHAR));
