Custom album.nfo is not working

[whisper.sunrise1043]

What's wrong with my files, I wanted to add my audiobook as Music files but something doesn't work with metadata.

It loads my artist.nfo file correctly but album.nfo doesn't work.

File structure:
Audiobooks:
> Artist Name
> > artist.nfo https://pastebin.com/raw/Xw3Q6zhJ
> > Audiobook Name
> > > album.nfo https://pastebin.com/raw/e9kYfhm8
> > > Files.mp3

Any reason you are placing audio books in a music library and not a book library? A book library does accept audio files and will track progress while a music library will not.

Regarding your question about NFOs. I've never used them with audio so I am not sure how a books library, or a music library, will interpret NFOs.

What you can experiment with is removing the NFOs (back them up) and asking Jellyfin to generate NFOs so you can compare how Jellyfin uses NFOs in this context vs what you've created.

I put these files in the music library because the metadata wasn't working either in books. 
I had already experimented with Jellyfin to generate them, but in most cases, it didn’t create anything - and when it did, the files were incomplete. 

I wrote a Python script to organize everything the way I wanted, since I didn’t want to use Jellyfin’s NFO files (my script is based on NFO generated from Jellyfin so).

Edit 1
I have look through the Jellyfin source code and don't even see an NFO parser for audiobooks

Edit 2
I think the problem is the text encoding of file names, folders etc.
