Question

How to display text in top-down languages (Japanese, Chinese, etc.) on iOS and Android?

For iOS, I've found this: https://github.com/novi/LTCoreText ... Any other alternative for iOS?

For Android, I cannot find any library/framework. Does anyone know?

You may use a custom view to draw text on it vertically, just like below screenshot, these are traditional Mongolian script.

public class DrawTextView extends View {

    @Override
    protected void onDraw(Canvas canvas) {

    .....
    }
}
