I realize this is a really dated thread, however it's exactly what I need. I've tried using the latest version of this script that I can find and it gives me really tags sometimes. For example, on this page
The kanji versions like 夢☆ONCE AGAIN, display as 螟｢笘・NCE AGAIN on Mp3tag. Track 8, ここで待ってるよ displays as 縺薙％縺ｧ蠕・▲縺ｦ繧九ｈ.
I can't figure out why this is happening, but it's happening more often than not on the albums I've tried, but not all. For example, http://vgmdb.net/album/39348 works perfectly with mp3tag, everything displays as it should with the kanji intact. Any ideas would be great.
I'm really anal about tagging and probably spend weeks of my life a year doing it. I wish i discovered mp3tag years ago, so even if I cant get this resolved it still be cut a ton of time out of the process thanks to other scripts and this one when it works.
