Discussion

Media options with forced-only subtitles are typically selected when 1) the user has not selected a legible option with an accessibility characteristic or an auxiliary purpose and 2) its locale matches the locale of the selected audible media selection option.

The value of this characteristic is "public.subtitles.forced-only".

The presence of this characteristic for a legible media option is inferred from the format description of the associated track that presents the subtitle media.
