An experiment about coding (C # written Notepad document, read in C + + under Linux)

First step: Generate TXT documents in C # with various types of encoding

using System.IO;

namespace WordTest
{
    class Program
    {
        static void Main (string [] args)
        {
            string text1 = "wa jue ji ji shu dao di na jia qiang? \ r \ n";
            string text2 = "Which digger technology is the best? \ r \ n";
            string text = text1 + text2;

            using (StreamWriter sw = new StreamWriter (
                "testASCII.txt", false, Encoding.ASCII))
            {
                sw.Write (text);
                Console.WriteLine ("Encoding.ASCII finished writing");
            }

            using (StreamWriter sw = new StreamWriter (

            {
                sw.Write (text);
                Console.WriteLine ("Encoding.BigEndianUnicode finished writing");
            }

            using (StreamWriter sw = new StreamWriter (

            {
                sw.Write (text);
                Console.WriteLine ("Encoding.Unicode finished writing");
            }

            using (StreamWriter sw = new StreamWriter (

            {

                Console.WriteLine ("Encoding.UTF7 finished writing");
            }

            using (StreamWriter sw = new StreamWriter (
                "testUTF8.txt", false, Encoding.UTF8))
            {
                sw.Write (text);
                Console.WriteLine ("Encoding.UTF8 finished writing");
            }

            Console.ReadLine ();
        }
    }
}

Program Run Result:

Step two: Copy to a redhat system and read the contents of these TXT documents with the cat command

Step three: read out the contents of these TXT documents in C + +

Program code:

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
    ifstream cin1("testASCII.txt");
    char s1a[100];
    char s1b[100];
    cin1.getline(s1a, 100, ‘\n‘);
    cin1.getline(s1b, 100, ‘\n‘);
    cout << "ASCII:" << endl << s1a << endl << s1b << endl << endl;

    ifstream cin2("testBigEndianUnicode.txt");
    char s2a[100];
    char s2b[100];
    cin2.getline(s2a, 100, ‘\n‘);
    cin2.getline(s2b, 100, ‘\n‘);
    cout << "BigEndianUnicode" << endl << s2a << endl << s2b << endl << endl;
    
    ifstream cin3("testUnicode.txt");
    char s3a[100];
    char s3b[100];
    cin3.getline(s3a, 100, ‘\n‘);
    cin3.getline(s3b, 100, ‘\n‘);
    cout << "Unicode" << endl << s3a << endl << s3b << endl << endl;

    ifstream cin4("testUTF32.txt");
    char s4a[100];
    char s4b[100];
    cin4.getline(s4a, 100, ‘\n‘);
    cin4.getline(s4b, 100, ‘\n‘);
    cout << "UTF32" << endl << s4a << endl << s4b << endl << endl;

    ifstream cin5("testUTF7.txt");
    char s5a[100];
    char s5b[100];
    cin5.getline(s5a, 100, ‘\n‘);
    cin5.getline(s5b, 100, ‘\n‘);
    cout << "UTF7" << endl << s5a << endl << s5b << endl << endl;

    ifstream cin6("testUTF8.txt");
    char s6a[100];
    char s6b[100];
    cin6.getline(s6a, 100, ‘\n‘);
    cin6.getline(s6b, 100, ‘\n‘);
    cout << "UTF8" << endl << s6a << endl << s6b << endl << endl;

    return 0;
}

Operation Result:

Conclusion: ASCII-encoded files can read English characters, UTF8 encoded files, C + + in Linux can read Chinese and English
