Im using Debian 10, installed today.
So, japanese characters (hiragana, katakana and kanji) are not showing in my Spotify, instead, it is showing someting like a blank space
But when i try to edit the playlist name, and i do a CTRL+A -> CTRL+C i get the right name: クラリス と TrySail と LiSA と SILENT SIREN.
It is also not working in search and lyrics, same problem, a blank space.
Im using the most recent version of Spotify (snap)
Version 1.1.46.916.g416cacf1
