Does iTunes Support Unicode?

I'm not completely sure that song was Japanese actually.

These two are definately Japanese. They should say something like:
"Studio Pixel" (picture [http://img43.imageshack.us/my.php?image=picture3hiv.png])
"Cave Story" (hiragana is どうくつ　ものがたり)


…J‰–⁄ºPixel
„´‘A¨‘ê∞T∞E∞„∞h∞g∞≈∞b∞N

I found an app called ID3Mod2 that fixed the songs. It has a huge list of character encodings that can be punched into the ID3 tag. Through trial and error I found an encoding that worked.

ShiftJIS
