Hello I am a newbie in Processing, how can I input Japanese font in my sketch?

Kaashdivitre

I am trying to execute a program where it shows japanese characters in output. However, when I am coding and copy paste the japanese text, it just shows BOXES. I enabled the complex text input in preferences too but it is not helping me either. Can someone please help me through?

CODE:-

PImage[] birds = new PImage[22];
PFont title;

void setup(){

  size(720,540);
  for (int i = 1; i < birds.length; i ++)
   {
    birds[i] = loadImage( i +".jpg");
   }

   frameRate(5);
   title=loadFont("07LightNovelPOP-48.vlw");
}

void draw(){

  int index=int(random(1,22));
  image(birds[index],0,0);
  textFont(title);
  textAlign(CENTER, CENTER);
  textSize(88);
  text("何何何何何何何何", 320, 180);


}

ERROR:- No glyph found for the 何 (\u4F55) character

Did you use createFont and font

@GoToLoop

Thanks a lot. I changed my code and it is properly formatted. However, I am still trying to comprehend the other two links you sent related to Japanese characters, it's littler hard to comprehend as I am totally new to programming. I am seeing it right now what it says. I hope i get it. Thanks again.

Hello @GoToLoop I tried to understand that code but it prints the japanese character in console itself. How do I show it sketch output?

// UTF_8, UTF_16, ISO_8859_1, US_ASCII:
import static java.nio.charset.StandardCharsets.*; //THIS IMPORTS ALL THE NECESSARY CHARACTER ENCODE?

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();

Do we have to then create the font and text(char, float, float) to show it in output?

Sorry for poor english I hope I am clear.

That 1st example is for converting Java's UTF-16 String to UTF-8.
2nd link example shows that not every font is capable of displaying the full Unicode characters.

@Kaashdivitre -- re:

Look at these two reference pages -- the difference between writing text to the console with println(), and drawing it on the screen with text():

2. https://processing.org/reference/text_.html
