Unicode (UTF-8) tags

Hi,

I have quite a few albums with artist, titles and tracks that are
non-ASCII. The default for ID3 tags seems to be ISO-8859.1 (Latin1), so as
long as this fits it's okay. But several albums use non-Latin1
(e.g. ISO-8859.2). Fortunately ID3v2 supports Unicode.

I would like to use UTF-8 data (since that is what I have at hand) so this
would require ID3v2.4.

So the questions are:

1. Does LMS handle ID3v2.4?

2. What (linux) command line tools are suitable for adding/retrieving
ID3v2.4 tags with UTF-8 data?

I did some experiments and some ID3v2.4 taggers seem to produce misbehaving
files (i.e. behave as if they had no tags at all).
