What you ask is certainly possible, but as always you have to know what you're doing. Unicode is a mere newcomer, when compared to C, ASCII, and Windows. > to a text file to be pretty much the default behavior. If you have anyĬompliments or complaints to MSDN Support, feel free to contact Since Unicode is the standard (and has been for years), I would have expected writing Unicode text This can be beneficial to other community members reading this thread.

UOpenFlag |= CFile::typeBinary // Unicode need add CFile::typeBinaryīOO元2 bRet = logFile.Open(pszFilePath, uOpenFlag, &ex) įlog.Write((void*)&unicodeFlag, sizeof(WORD)) UINT uOpenFlag = CFile::shareDenyNone | CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate If (pszLog = NULL || pszFilePath = NULL)īOOL bFileExsit = PathFileExists(pszFilePath) void WriteLog(LPCTSTR pszLog, LPCTSTR pszFilePath) I have found a sample about using CStdioFile. At the very least, this is a jarring inconsistency, as CString can contain UNICODE, and ofstream canĪccept CString input, for example: CString Test = _T('abc') The fact that FILE supports UNICODE, UTF-8 & UTF-16, while ofstream does not is a clear indication that VS does not, yet, fully support UNICODE. In addition to this modification, I had to ensure that the file was explicitly closed, as ofstream files are closed automatically when the deconstructor is called, but FILE files are not! I also was able to remove the code to write BOM to the file,Īs this is automatic with FILE when css=UNICODE or UTF-8 or UTF-16. The basic idea is to open the file with: FILE *fStream Įrrno_t e = _tfopen_s(&fStream, TargetFile, _T('wt,ccs=UTF-8')) ĪfxMessageBox(_T('Export file cannot be opened'), MB_ICONINFORMATION) ĬStdioFile File(fStream) // open the file from this stream Full disclosure, a coworker pointed me to this solution, which he obtained from StackOverflow: As it turns out, the answer is fairly simple, as I expected it should be.
