Using other language in controlP5 textfield

Yuk

Hello
I'm recently working on a processing project and now i got some trouble because of my language.
i'm trying to get Korean language in a textfield using controlP5.
However i have trouble to get Korean language in the textfield.
Is there any solution?
This is the code below.

import controlP5.*;

ControlP5 cp5;
String textValue = "";

void setup(){
  PFont font = createFont("arial",60);
  cp5 = new ControlP5(this);
  cp5.addTextfield("")
  .setPosition(width/4,(height/3)*2)
  .setSize(800,80)
  .setFont(font)
  .setFocus(true)
  .setLabelVisible(true)
  .setColor(color(255,255,255))
  .setColorBackground(color(255,255,255,150));
}

Thank you.
