I have a simple question to ask. I have a UTF 16 text file to read wich starts with FFFE. What are the C++ tools to deal with this kind of file? I just want to read it, filter some lines, and display the result.
It looks simple, but I just have experience in work with plain ascci files and I'm in the hurry. I'm using VS C++, but I'm not want to work with managed C++.
Regards
Here a put a very simple example
wifstream file;
file.open("C:\\appLog.txt", ios::in);
wchar_t buffer[2048];
file.seekg(2);
file.getline(buffer, bSize-1);
wprintf(L"%s\n", buffer);
file.close();
You can use fgetws, which reads 16-bit characters. Your file is in little-endian,byte order. Since x86 machines are also little-endian you should be able to handle the file without much trouble. When you want to do output, use fwprintf.
Also, I agree more information could be useful. For instance, you may be using a library that abstracts away some of this.
Since you are in the hurry, use ifstream in binary mode and do your job. I had the same problems with you and this saved my day. (it is not a recommended solution, of course, its just a hack)
ifstream file;
file.open("k:/test.txt", ifstream::in|ifstream::binary);
wchar_t buffer[2048];
file.seekg(2);
file.read((char*)buffer, line_length);
wprintf(L"%s\n", buffer);
file.close();
