Problem with encoding in console and file?

Question

Java

I read the data from the file, the Russian characters turned into squares when I printed them to the console, I thought that I would write to the file ok, but there I also
read the squares like this in a utf-8 file like this:

Z:\Автоматизация\музыка для радио \Solarsoul\[2013] Defying Gravity [AR0003] WEB\11. Solarsoul - UDFy (13 Billion Light Years From Earth).mp3

code line by line

try {
            File file = new File("C:\\Users\\User\\source\\repos\\Project1\\Project1\\playlist4.m3u8");
            //создаем объект FileReader для объекта File
            FileReader fr = new FileReader(file);
            //создаем BufferedReader с существующего FileReader для построчного считывания
            BufferedReader reader = new BufferedReader(fr);
            // считаем сначала первую строку
            Type tmp = new Type();
            tmp.length = (float) 0.0;
            tmp.name = "";
            String line = reader.readLine();
            while (line != null) {
                tmp.name = line;
                line = reader.readLine();
                tmp.length = Float.parseFloat(line);
                music.add(tmp);
                //System.out.println(tmp.name+"\n"+tmp.length);
                // считываем остальные строки в цикле
                line = reader.readLine();
                tmp = new Type();
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

I write like this

try(FileWriter writer = new FileWriter("playlist.m3u8", false))
        {
            writer.write("#EXTM3U\n");
  for (int i = 0; i < vec.size(); i++)
  {
    writer.write("#EXTINF:");
    writer.write((int)vec.get(i).length);
    writer.write(",");
    writer.write(vec.get(i).name);
    writer.write("\n");
    writer.write(vec.get(i).name);
    writer.write("\n");
  }    
            writer.flush();
        }
        catch(IOException ex){
             
            System.out.println(ex.getMessage());
        }

Answer 1

The file encoded "windows-1251" was a little mistaken

try {
            File file = new File("C:\\Users\\User\\Desktop\\Tropic-Island\\Tropic-Island\\C++\\Project1\\Project1\\playlist4.m3u8");
            //создаем объект FileReader для объекта File
            //FileReader fr = new FileReader(file);
            
      FileInputStream fStream = new FileInputStream(file);
            InputStreamReader fr = new InputStreamReader(fStream, "windows-1251");
            //создаем BufferedReader с существующего FileReader для построчного считывания
            BufferedReader reader = new BufferedReader(fr);
            // считаем сначала первую строку
            Type tmp = new Type();
            tmp.length = (float) 0.0;
            tmp.name = "";
            String line = reader.readLine();
            while (line != null) {
                tmp.name = line;
                line = reader.readLine();
                tmp.length = Float.parseFloat(line);
                music.add(tmp);
                //System.out.println(tmp.name+"\n"+tmp.length);
                // считываем остальные строки в цикле
                line = reader.readLine();
                tmp = new Type();
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

just in case, the result was also written in this encoding

try(Writer writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("playlist.m3u8"), "windows-1251")))
        {
            
            writer.write("#EXTM3U\n");
  for (int i = 0; i < vec.size(); i++)
  {
    writer.write("#EXTINF:");
    writer.write(Integer.toString((int)vec.get(i).length));
    writer.write(",");
    writer.write(vec.get(i).name);
    writer.write("\n");
    writer.write(vec.get(i).name);
    writer.write("\n");
  }    
            writer.flush();
        }
