[JAVA] Issues formatting auth

I got the system working by using;

pw.println(new String("some text".getBytes(), "UTF-8"));

for the entire authentication process. So the new code looks something like this:

public String start() throws IOException {
	String toReturn = "";
	if(TWITCHCOMM.isConnected()) {
		PrintWriter pw = new PrintWriter(new OutputStreamWriter(TWITCHCOMM.getOutputStream(), StandardCharsets.UTF_8),true);
		pw.println(new String(("PASS " + (Main.isRedCase ? Main.OAUTH[0] : Main.OAUTH[1]) + Commands.END).getBytes(), "UTF-8"));
		pw.println(new String(("USER firstwa_" + (Main.isRedCase ? "red" : "blue") + Commands.END).getBytes(), "UTF-8"));
		pw.println(new String(("NICK firstwa_" + (Main.isRedCase ? "red" : "blue") + Commands.END).getBytes(), "UTF-8"));
		pw.println(new String(("JOIN #" + CHANNEL + Commands.END).getBytes(), "UTF-8"));
		pw.flush();
		System.out.println("Connector Data Sent");
		BufferedReader br = new BufferedReader(new InputStreamReader(TWITCHCOMM.getInputStream()));
		String update = "";
		while((update = br.readLine()) != null && !update.toLowerCase().contains(":end of /names list")) {
			toReturn += update.indexOf("\r\n") > update.length()-10 ? update.substring(0, update.indexOf("\r\n")) : update;
			toReturn += "\n";
		}
		pw.close();
	} else {
		toReturn = "Connection Failed.";
	}
	return toReturn;
}

Thanks all!
