Reading Unicode text files.

From: David Webber on 14 Jan 2010 07:25 I am getting increasingly frustrated at the shortcomings of CStdioFile for reading Unicode text files (unless I've missed something). I've found a nice looking class on CodeProject <http://www.codeproject.com/KB/files/textfiledocument.aspx> but it is several years old. Has something been introduced into MFC to do this sort of thing in the last couple of Visual Studio releases? If not, is there something in the Win32 API or CRT?

I would suggest CStdioFileEx on CodeProject: http://www.codeproject.com/KB/files/stdiofileex.aspx Moreover, since VS2005, there is a Unicode support in CRT for _open and _wopen, see _O_U16TEXT, _O_U8TEXT and _O_WTEXT flags. http://msdn.microsoft.com/en-us/library/z0kc8e3z(VS.80).aspx And, FWIW, some time ago, I shared some code to read and write UTF8 on CodeGallery as well: http://code.msdn.microsoft.com/UTF8Helpers HTH, Giovanni

Thanks - I've just discovered it in fopen() and friends too, with an enhanced 'mode' parameter. The documentation is about as clear as mud when it comes to binary or text mode, but a bit of experimentation should sort that out. > http://msdn.microsoft.com/en-us/library/z0kc8e3z(VS.80).aspx > > And, FWIW, some time ago, I shared some code to read and write UTF8 on > CodeGallery as well: > > http://code.msdn.microsoft.com/UTF8Helpers I'll try to remember that too, but at the moment I only need to read single-byte text files with the Western European character set, or UTF-16 (in fact more specifically UCS2). (I have a data base of musical instrument properties in a .txt file which comes in different language versions. So far single byte stuff with the Western character set has been fine, but I want to add a Czech version. UCS2 will be fine for this. All I need is code to read either encoding transparently into wchar_t strings.)

Hi David, I agree and I also use the CStdioFileEx from http://www.codeproject.com/KB/files/stdiofileex.aspx although I've redone a lot of it because I needed UTF-8 as well (it is a really good starting point). I wish they'd put something like this into MFC's version.
