I’ve noticed Eter titles sometimes don’t handle special characters correctly. I happened to catch some photos of a title in Eter and then showing that same title correctly displayed in the radio station’s (KEXP, US) official iOS app. Of course, this might just be an issue with the stream metadata.
I will look into that. As a Pole, listening to our local stations with metadata full of Polish diacritics I haven’t noticed that but I will definitely check it.
