[Bug] Next song fails with "FAILED TO QUERY METADATA" when previous downloaded track has unicode chars in name or author ("incomplete escape \U at position 3")

[mkorning]

Description:
Given a playlist with at least 1 song with foreign unicode chars in song title and/or album name and/or author, when the playlist is downloaded via zotify, the physical song with unicode chars will download, however the metadata wil fail to download and this will cause the next song to fail to download and return
## SKIPPING SONG - FAILED TO QUERY METADATA ###

...Followed by
incomplete escape \U at position 3

Note that with some song names with unicode chars, the next 3 songs (which do not have unicode) will fail for download, but for some others it's only the next single song (also without unicode) - (possibly due to variable byte-length of specific chars). Then after these 1-3 track failures, download recovers and succeeds on the next track(s) - unless other songs in the playlist also have unicode. I have repeated this with many playlists (with 1 or more unicode chars in track names) and I get the same result.

e.g.:
This playlist: https://open.spotify.com/playlist/3cMXTkP11GBDoNitE7jtJk?si=963050a5ecf946b3
Containing this artist/song at track #4: "Myrkur - Två Konungabarn (Single)"
