Send Japanese characters stored into a String to a byte array (with split)

olivi55

Hi ! I have to use Japanese characters in my program, and send them via a COM port...I tried debugging to check the value of my String, and the Japanese character is inside, but the problem is when I convert to a string of bytes to port.write() it (using data=String.getBytes() ) ,when it comes to the Japanese character it transforms it in a "?"...is there a way to make getBytes() (or any other function of the same type) split this one japanese character in the multiple bytes needed ? Thx forward

getBytes(): http://docs.Oracle.com/javase/8/docs/api/java/lang/String.html#getBytes-java.nio.charset.Charset-

import java.nio.charset.Charset;

static final String JAP = "富士の風や扇にのせて江戸土産";
static final String ENCODE = "UTF-8"; // or "UTF-16"
static final Charset UTF = Charset.availableCharsets().get(ENCODE);

void setup() {
  final byte[] send = JAP.getBytes(UTF);
  println(JAP, UTF, JAP.length(), send.length); // UTF-8 14 42
  exit();
}

@olivi55, just found out there's an even shorter & easier approach: StandardCharsets: \m/
http://docs.Oracle.com/javase/8/docs/api/java/nio/charset/StandardCharsets.html

// UTF_8, UTF_16, ISO_8859_1, US_ASCII:
import static java.nio.charset.StandardCharsets.*;

String JAP = "富士の風や扇にのせて江戸土産";
byte[] send = JAP.getBytes(UTF_8);

println(JAP, UTF_8, JAP.length(), send.length); // UTF-8 14 42
exit();
