mpd: tags to utf-8

The solution isn’t mine, I found part of it here
So if you have lots of troubles in viewing tags, first you need mutagen or in my case with Gentoo:

1. emerge --oneshot mutagen

Then edit /etc/mpd.conf or ~/.mpdconf:

1. id3v1_encoding "UTF-8"

Then in directory with your music run:

1. find -iname '*.mp3' -print0 | xargs -0 mid3iconv -eCP1251 --remove-v1

This will convert all tags in mp3 files from CP1251 encoding, or you can specify needed encoding after -e option
