Sorry if this is a repost, but thought it might be useful for this group. Someone (not me) made this cool spreadsheet listing films and TV and weather english subtitles are built in or forced, so if you are backing things up for plex you can determine if you need to use a tool like MKVToolNixGUI to force various subtitle tracks. This is especially useful for movies where the film has a few lines of foreign language (or made up language) dialog that wouldn't be shown if you just ripped and had no sub tracks enabled. I originally found it when backing up my GoT collection, but it's been useful for so many films!

Disk subtitles spreadsheet
Re: Disk subtitles spreadsheet
Seconded. I use this then do a (English) (Foreign Only) filtered search on Subscene if I want confirmation.
