My music library includes files with Funky Unicode Names and I have no idea if it's Android, KDE/Dolphin, or the SD card but it regularly eats entire albums and doesn't show them in the media library nor file browsers even though the files exist.
I mention KDE because as far as I remember this didn't happen on Windows. I'll have to try and copy them via MTP on it. MTP transfers of these cursed files always fail on Dolphin.
