I have created a small application that allows you to extract the "FORCED" subtitles from the .sup subtitle files that you have extracted from your BD/UHD discs. I tested it out on a few of my own .sup files that I extracted from some BD/UHD discs.
This works on windows only and .net framework 4.5 or higher is required (so Win10 users should be fine).
It is a "1-click" application and is simple to use. Just run the exe, click the "OPEN" button and select a .sup subtitle file. That's it! The 'Info' window will let you know how many subtitles are in the file and how many are flagged as 'forced' (if any). At the same time, if there are any 'forced' subtitles, the application will extract them to a file in the same directory as the source file.
I thought this might be helpful for someone, so please, give it a try and let me know if you run in to any issues...
EDITS:
30.11.2019 - Fix: Files that only contain forced subtitles to begin with were not copied correctly. Updated file attached.
24.01.2020 - Update: You can now 'drag and drop' your .sup source file onto the textbox.

Oh, I added a donation button to the application just in case anyone is feeling generous!!
Cheers!
