Hi I am new on C++ but I have experience on other languages
I have the following code:
        streampos begin,end;
        char delimeter[3] = {',', '\n', '\0'};
        int numChars = 0;
        int pos1 = 0, pos2 = 0, pos3 = 0, startIndex = 0, studentIndex = 0;
        ifstream file1("Students1.csv", ios::in);
        if (!file1) throw MyExceptions();
        begin = file1.tellg();
        file1.seekg (0, ios::end);
        end = file1.tellg();
        int size = end - begin;
        file1.seekg(0, ios::beg);
        char charField[size];
        while(file1.getline(charField, size, '\n'))
        {
            char *tmpCharField1 = charField;
            numChars = file1.gcount();
            CustomString tmpStudent(tmpCharField1, numChars);
            pos1 = tmpStudent.findCharacter(&delimeter[0], startIndex);
            CustomString tmpStudentCode = tmpStudent.subString(startIndex, pos1);
            pos2 = tmpStudent.findCharacter(&delimeter[0], (pos1 + 1));
            CustomString tmpFirstName = tmpStudent.subString((pos1 + 1), pos2);
            pos3 = tmpStudent.findCharacter(&delimeter[2], (pos2 + 1));
            CustomString tmpSecondName = tmpStudent.subString((pos2 + 1), pos3);
            Student *student1 = new Student(tmpStudentCode, tmpFirstName, tmpSecondName);
            this->StudentVector.push_back(student1);
            studentIndex++;
        }
        file1.close();

I am trying to read a file with Greek letters where the file is as this:
SR000001,ΕΠΩΝΥΜΟ 0001,ΟΝΟΜΑ 0001
SR000002,ΕΠΩΝΥΜΟ 0002,ΟΝΟΜΑ 0002
SR000003,ΕΠΩΝΥΜΟ 0003,ΟΝΟΜΑ 0003
SR000004,ΕΠΩΝΥΜΟ 0004,ΟΝΟΜΑ 0004
SR000005,ΕΠΩΝΥΜΟ 0005,ΟΝΟΜΑ 0005
SR000006,ΕΠΩΝΥΜΟ 0006,ΟΝΟΜΑ 0006
SR000007,ΕΠΩΝΥΜΟ 0007,ΟΝΟΜΑ 0007
The format is on UTF8, I use NetBeans 8.1 on Windows 10 64 bit machine with MINGW-64. How can I read the Greek letters as 1 byte data? Please do not say me that the reading is not ok, I have to do an assignment without using string or string methods…
