What happened?

it seems when the mp3-tag 'album title' contains umlauts (üöä), these audiobook-names contain � instead of the umlauts (üöä) in their title.

What did you expect to happen?

audiobookshelf web+app should display the 'real' name, instead of substituting these umlauit-characters with �

Steps to reproduce the issue

  1. add some audiobook which contains umlauts as 'album title'
  2. update the library
  3. check audiobook-names in webif+app

Audiobookshelf version

v2.28.0

How are you running audiobookshelf?

Debian/PPA

What OS is your Audiobookshelf server hosted from?

Linux

If the issue is being seen in the UI, what browsers are you seeing the problem on?

Firefox

Logs


Additional Notes

  • debian trixie
  • characters are shown wrong in webif+android app

For me the Umlauts show up fine. It's probably an issue with the encoding of the tags in your files.

What software did you use to tag your files? Make sure your tags are utf-8 encoded, not cp1252.

hm - any advice how to check for the current id3-tag encondig?
tried with kid3 ,mp3guessenc ,mp3info and mp3unicode - but no luck.
half of these tools show correct umlauts and the other half 'faulty' characters instead.

I use mp3tag for tagging.

Mostly people are not interested in what the encoding is, mp3tag will not show you either I think.

mp3tag encodes tags in utf by default on writing. Open your files in mp3tag, fix the tags if there are issues and hit save. Your tags should be properly read by ABS and the tools you mentioned above.

cant get write-permissions to these server-side files to change the id3-tags :/
since playback works from these 'malformed' displayd encoding, i'll close this issue - just wanted to report the 'bug'

installed mp3tag by using wine and when checking the file, the album-tag is displayed correct?!
