With C#, it is very easy.

StreamReader sr=new StreamReader("c:\\a.txt",Encoding.UTF8);
string line=sr.ReadLine();
sr.close();
MessageBox.Show(line);

But with unmanaged Visual C++, I couldn't even find a simple example.
I tried to use wifstream.getline but it didn't read Asian characters
correctly.
I've searched for the news groups for an answer but I all I found was
that
I might have to buy a third party library just to do that.
Do I really need to buy a library just to read simple UTF-8 text file?
(Of course, in case I don't know how to create an equivalent library
myself)

If not, could you plelase tell me the VC++ equivalent code for the C#
code above?
Thank you.

Sin:

UTF-8 uses 8-bit chatracters, so you should use ifstream not wifstream.
Use MultiByteToWideChar to convert to UTF-16. If your app is ANSI
compiled (I hope not) then use WideCharToMultiByte() to get the local
code page.

Thank you, I'll try that.
