Does anyone know of a (small) tool that shows id3 tags
and can tell what encoding is used? (latin1 vs utf-16 vs utf-8),

Im struggling with mp3's which are (i think) encoded as utf-8,
but using iso8859-1 encoding headers.

It would even be nicer if such a tool could detect these
errors and/or be able to fix them.

linux/command line/open source preferred, but a Windows
GUI tool would be fine too.

Thanks,
Pim
