[Bug]: Incorrect Subtitle Encoding in Stremio TV App

Describe the bug

Dear Stremio Development Team,

I’m experiencing an issue with subtitle encoding on the Stremio TV app. Special characters like Č, Ć, Đ, Š, Ž in SRT subtitles are not displayed correctly when streaming content from my Plex server using the Plexio addon.

Key details:

1. All SRT subtitle files are properly encoded as UTF-8 without BOM.
2. The subtitles display correctly on the Stremio mobile app
3. On the Stremio TV app, the subtitles appear with incorrect characters when using the default ExoPlayer.
4. If I switch the player to libvlc, the subtitles display correctly, but the video gets cropped, cutting off part of the picture, making it an impractical solution.

It seems like the Stremio TV app's ExoPlayer is not interpreting the UTF-8 encoding properly when displaying subtitles. This issue might be related to how the app handles the Content-Type header for text/plain without explicitly specifying charset=utf-8.

Could you please investigate this issue and consider fixing the subtitle encoding behavior in the ExoPlayer on the Stremio TV app?

To add, this issue occurs on almost all TV versions of the app, including Android, Samsung, LG, and others.

Thank you in advance for your support!

Best regards,
Nebojša
