Hm, also, I tried to play with the codepage conversion parameter. Didn’t really find a setting that fits.
Also googling didn’t actually reveal a tool to identify the codepage an ID3 tag is encoded in? (neither id3v1, id3v2)
At least this setting seems to do something.
When I set it to ISO-8859-1 Im getting other _weird_ characters instead of, say, german umlauts.
I think the proble might be that my mp3 library spans quite some years, and thus lots of sources for tags. I remember old ones using XING mp3 encoder, mp3enc, lame, mp3compressor etc etc. So likely there is a huge variety of encodings. I’ve got used to it, kinda, though. 😉
