[Bug]: Cover Art missing in folders that contain the U+200B character

[pimzand]

I confirm that:

• [X] I have searched the existing open AND closed issues to see if an issue already exists for the bug I've encountered
• [X] I'm using the latest version (your issue may have been fixed already)

Version

0.50.2-1.fc39 (source_archive)

Current Behavior

When any part of the path ends with Unicode character U+200B (Zero Width Space), no cover art will be shown for that music.

Expected Behavior

Any path valid for storing music files should also be valid for storing cover art files.

Steps To Reproduce

1, create a folder ending with U+200B. Populate it with valid content; in my case .flac files and a folder.jpg cover art file

2. witness that the music files can be played, but the cover art is not detected
3. rename the folder by removing the U+200B character
4. witness that the cover art is now properly shown

Environment

- OS: Fedora 39
- Browser: Firefox
- Client: Fedora 39

Anything else?

In all the error messages above, the first part of the path is missing. These are all R.E.M. albums, which are located in folder /music/main/R.E.M.(U+200B) The U+200B character was appended by my CD ripping program, to prevent creating folders that end with a dot, which would be illegal in Microsoft Windows, making it impossible to share the folder with Windows clients.

Hey, sorry for the delay. We currently use the Zero-width space char (U+200b) as a path separator for cover art paths. This is the root cause of the issue.

In the new Scanner (#2709), I'm using JSON lists to store lists in the DB, so this will be solved.

Interesting choice from your CD ripping program... Usually when a program needs to escape the . in the last char, it is replaced with _:

Anyway, the only workaround for now is to remove such chars from the file/dir names.

[pimzand]

Thanks for finding the cause. I will be happy to wait for a build that fixes this. My CD ripping program https://github.com/jack-cli-cd-ripper/jack/ allows me to configure what to do with trailing dots using regex replacements. I chose U+200b myself because it does not visually change the name of the artist or album.
