Textfield support ios native font, chinese traditional, chinese simplifield, japanese and korean languages

Hi,
I have problem with textfield on iOS.
Chinese traditional, chinese simplifield, japanese and korean languages display as squares.

var format = new TextFormat ("_sans", 30, 0x7A0026);
var textField = new TextField ();
textField.defaultTextFormat = format;
textField.embedFonts = true;
textField.selectable = false;
textField.x = 50;
textField.y = 50;
textField.width = 200;
textField.text = “모든 토템을 다시 회수해야 합니다”;
addChild (textField);

I hope anyone know how use native fonts in iOS for support multiple languages.
Thanks

Are you sure your “_sans” font supports the chinese symbols?

There are a few things required to improve UTF-8 support

We need to use an abstract inside the OpenFL TextField, I believe, to workaround issues with UTF-8 support in Haxe

Also, we need to see if Cairo supports UTF-8 text, or if we need to use Harfbuzz and a different renderer
