Renaming does not work with Nordic characters

When I try to use move and rename. I want to be able to add Nordic characters, but it doesn't work.

“åäö ÅÄÖ” becomes ? question mark with a twisted square behind it instead.

Move and rename with Unicode characters Works fine for me.

I'm on Windows 11 and using Advanced Renamer, version 4.19.

The folder name in File Explorer appears to be correct, but when it is displayed in Plex (docker), it behaves in this manner.

If it displays correctly in explorer but not in Plex (docker), then that is proof that Plex (docker) is not handling a valid explorer format correctly.

Does Plex (docker) display hand-renamed files correctly? Does it have Unicode support and is it enabled?

Personally, I'm not going to install Plex (docker) just to troubleshoot this. But if you are a paid Aren licensee, Kim might be willing to do more if you contact him via email support.

Good luck and I suggest you bring this up with the Plex (docker) people too. It really does appear to be on their end based on what you've said.

I may be wrong, but I think you can contact Kim Jensen for support even if you don't have a licence. The version comparison page only specifies that support priority is given to the paid version.
