Only English ABC characters containing songs are deleted by Playlist--File Remover.
If any ♥, (♦) (♣)(♠) + extended emoji symbols or Japanese, Chinese letters are in the songs or in the path because the FOLDER name is containing them, then File Remove is unable to delete the song from the playlist.
Example:
"H~ , EL&💙_شيرين- _ (Official Audio ) 💔_@sherine.flac"
If you can feed WACUP to play these songs, can you also instruct the plugin File Remover using the same internal "play this file name identifier" to also delete them?
