Answer 1

FileWriter fileWrite=new FileWriter("test.txt");
BufferedWriter bufferWrite=new BufferedWriter(fileWrite);
bufferWrite.write("test我喜欢深圳!");
bufferWrite.flush();

Answer 2

读取文本很少人用字节流操作
java.io.BufferedInputStream可以设置编码，可以设置编码还有什么不可以做的？

Answer 3

System.Text.Encoding enc = null;            using (System.IO.FileStream file = new System.IO.FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.Read))
            {
                if (file.CanSeek)
                {
                    byte[] bom = new byte[4]; // Get the byte-order , if there is one                     file.Read(bom, 0, 4);                    if(bom[0] == 0xef && bom[1] == 0xbb && bom[2] == 0xbf)
                    {
                        enc = System.Text.Encoding.UTF8;  
                    }
                    else if (bom[0] == 0xff && bom[1] == 0xfe)
                    {
                        // ucs-2le, ucs-4le, and ucs-16le
                        enc=System.Text.Encoding.Unicode;
                    }
                    else if(bom[0] == 0xfe && bom[1] == 0xff) 
                    {
                        // utf-16 and ucs-2
                        enc=System.Text.Encoding.BigEndianUnicode;
                    }
                    else if(bom[0] == 0 && bom[1] == 0 && bom[2] == 0xfe && bom[3] == 0xff)

                        enc = System.Text.Encoding.UTF32;

                    else
                    {
                        enc = System.Text.Encoding.ASCII;
                    }
                }
                else
                {
                    // The file cannot be randomly accessed, so you need to decide what to set the default to
                    // based on the data provided. If you're expecting data from a lot of older applications,
                    // default your encoding to Encoding.ASCII. If you're expecting data from a lot of newer
                    // applications, default your encoding to Encoding.Unicode. Also, since binary files are
                    // single byte-based, so you will want to use Encoding.ASCII, even though you'll probably
                    // never need to use the encoding then since the Encoding classes are really meant to get
                    // strings from the byte array that is the file.
                    enc = System.Text.Encoding.ASCII;
                }
                return enc;
            }
