Can't fonts loaded during openfl runtime be displayed?

I am a beginner in openfl and I use Assets.loadFont (“font. ttf”). onComplete (handleFont); Dynamically loading fonts during runtime, even HTML5 Windows can display fonts normally. Why are Flash and Air fonts not displayed when released? I can’t wait to know the reason and solution? I know embedding fonts in Flash Air can display them, but I don’t want to embed fonts. Do I need a method to dynamically load them at runtime? Seeking help from various gods???

Back when I used AIR I faced the very same problem and couldn’t find a real solution besides creating several swfs, each one with a font I’d like to use at runtime and load these swfs to get the fonts.
