custom subtitle font for non-latin language

I want to support non-latin languages on subtitle, for example, thai and chinese.

I can show these on label by setting custom font type, but there is no custom font option in captionStyle(https://developer.roku.com/docs/references/scenegraph/media-playback-nodes/video.md#closed-caption-fields).

Is there any way to set custom font on subtitle?

I’m sorry, this is not a feature of the Roku caption system at this time.

I think roCaptionRenderer component(roCaptionRenderer | Roku Developer) is what I looking for, but it is deprecated and app using this component will be rejected during certification.

Is there any alternative to show non-latin language?
