Invalid text encoding in file picker on Linux

[RKushnir]

Hello and thanks for this useful utility!

I'm bothered by a very disruptive problem with the file picker dialog:

Does the app expect a particular encoding? Can I somehow specify which encoding to use? There's no menu for configuration. Maybe through a config file?

I'm on Arch Linux with Xfce 4.18. Airdash installed via Snap.
