sockets - Java charset - How to get correct input from System.in? -

my first post here. well, i'm building simple app messaging through console(cmd , terminal), learning, i'm got problem while reader , writing text charset.

here initial code sending message, main.charset setted utf-8:

scanner teclado = new scanner(system.in,main.charset); bufferedwriter saida = new bufferedwriter(new outputstreamwriter(new bufferedoutputstream(cliente.getoutputstream()),main.charset))); saida.write(nick + " conectado!"); saida.flush(); while (teclado.hasnextline()) {     saida.write(nick +": "+ s);     saida.flush(); } 

and receiving code:

try (bufferedreader br = new bufferedreader(new inputstreamreader(servidor,main.charset))){     string s;     while ((s = br.readline()) != null) {         system.out.println(s);     } } 

when send "olá" or "ÁàçÇõÉ" (brazilian portuguese), got blank spaces on windows cmd (not tested in linux).

so teste following code:

scanner s = new scanner(system.in,main.charset); system.out.println(s.nextline()); 

and input "olá", printed "ol ".

the question is, how read console input read correctly , , can transmitted user , displayed correctly him.

if wanna output portuguese in text file, easy.

the thing have care display utf-8 encoding.

you can use simple way like

    string text = "olá";     filewriter fw = new filewriter("hello.txt");     fw.write(text);     fw.close(); 

then open hello.txt notepad or text tool support utf-8

or have change tool's default font utf-8.

if want show on console, think pvg answer you.

ok, seems still confuse on it.

here simple code can try.

        scanner userinput = new scanner(system.in);//type olá plz         string text = userinput.next();         system.out.println((int)text.charat(2));//you see output int 63                  char word = 'á'; // word covert int 225         int = 225;         system.out.println((int)word);// output 225         system.out.println((char)a);  // output  á 

so, conclusion?

if use console tpye in portuguese catch it, totally different word, not gibberish word.
