Getting a text file of asian characters with C++

I am completely new to programming, and I am teaching myself C++ via Dr. Bronson's book.

I have looked at other fixes and I don't understand them.

I am trying to do a project where I convert numbers to their phrase value. 1 = One, 2 = Two, etc. I cannot have spaces between one and two so I am outputting with no spaces. When I opened up the text file, I had only Asian characters in the file. Being a novice, my first concern was that I have been hacked. Anyhow, here is my code.

int main()
{
    int i; 
    int length, mod, number1, number2,number3,numbera,numberb; 
    string  str1;
    string filename = "C:\\Users\\miram\\OneDrive\\Documents\\Visual Studio 2017\\CPlusPlusProjects\\Project Euler\\Files\\17.WordSum1.txt";
    ofstream outFile; 

    outFile.open(filename.c_str()); 
    if (outFile.fail())
    {
        cout << "\nThe file named " << filename << " did not successfully open."
             << "\Please check to make sure the file exists."; 
    }


    for (i = 900; i <= 999; i++)
    {
        if (i <= 999)
        {
            length = (log(i) / log(10)) + 1;

            cout << "i: " << i << " " << length << endl;
        }

        else if (i == 1000)
        {
            length = 4;
            cout << "i: " << i << " " << length << endl;
        }


        if (length == 3)
        {
            number1 = i % 10; 
            numbera = i / 10; 
            number2 = numbera % 10; 
            numberb = i / 100; 
            number3 = numberb; 
            cout << "Number 3: " << number3 << endl; 
            cout << "Number 2: " << number2 << endl; 
            cout << "Number 1: " << number1 << endl; 
        }


        switch (length)
        {

        case 4: 
        {
        outFile << "OneThousand"; 
        break; 
        }

        case 3: 
        {
            if (number3 == 1)
            {
                outFile << "OneHundredand";
            }
            else if (number3 == 2)
            {
                outFile << "TwoHundredand";
            }
            else if (number3 == 3)
            {
                outFile << "ThreeHundredand";
            }
            else if (number3 == 4)
            {
                outFile << "FourHundredand";
            }
            else if (number3 == 5)
            {
                outFile << "FiveHundredand";
            }
            else if (number3 == 6)
            {
                outFile << "SixHundredand";
            }
            else if (number3 == 7)
            {
                outFile << "SevenHundredand";
            }
            else if (number3 == 8)
            {
                outFile << "EightHundredand";
            }
            else if (number3 == 9);
            {
                outFile << "NineHundredand";
            }
            break;
        }
        }


    }

    return 0; 
}
