MusicBrainz metadata encoding - incorrect symbols on Jellyfin metadata update

[coolikar]

Hello!

I'm trying to set up Jellyfin as a music library. Jellyfin instance is running in Docker on a Synology NAS.
I have an artist and one album on my NAS, which is stored in the correct folder structure as outlined here https://jellyfin.org/docs/general/server/media/music/ :
- /data/media/music/FliT
-- Світ такий… (2004)
--- FliT - Світ такий… - 01 - Може, ти знайдеш.mp3
--- FliT - Світ такий… - 02 - Вийди, моя люба.mp3
etc.

I'm using Lidarr for management, and the filenames above were directly copied from the NAS file management software (DSM - using Synology).
The folder names are correctly displayed in Jellyfin, but the album name and all the track names are incomprehensible.

   
   

I have MusicBrainz and The Audio DB metadata loaders enabled.
They have been correctly identified:
- https://musicbrainz.org/release/6b53e2a8...a18c91193b
- https://www.theaudiodb.com/album/2403538

The releases in MusicBrainz and The Audio DB have correct track and album names.
However, when Jellyfin loads them and applies to the tracks - they get butchered and the encoding is incorrect.
What could be causing this issue? How should I troubleshoot this?

The last piece of log when I attempted a "Refresh metadata" with "Replace all metadata" option:
  Log.txt (Size: 6.09 KB / Downloads: 31)

Any help would be appreciated.

Just FYI, I tried adding another album, and the encoding is correct, the album and track names are not gibberish: https://musicbrainz.org/release/341a0db3...379e86f86e

Can you tell if one album had embedded metadata and the other didn't?

I would gladly check this, but unfortunately I don't know how. I have checked what metadata is in the mp3 files of both albums, and it appears they both have the album and track names set (left is the bad one, right is the good one): https://imgur.com/a/K95l4iE

I guess try removing the problem music from the library folder, scan to remove them, move them back to the library and scan to re-add.

Also, can you check the docker environment variables? What is the value for DOTNET_SYSTEM_GLOBALIZATION_INVARIANT?
