Issues with playback of files with special characters in filename

Jellycon is not able to play files with special characters in filename. For example files containing the following characters: ěščřýáíú§ů and many more.

If I chose to transcode the movie the movie will be played.

I can also not remote control the Jellycon via the web interface and force to play the movie.

This is an issue as a huge part of my media library is in czech language and until now I did not need to rename the files after downloading so this would mean a huge time invest in manually find and rename the files.
