I have some songs that the tags are in traditional chinese. I computer (Win7) is able to display both simplified/traditional chinese at the same time. I can verify this by looking at some of my songs filename. However, in iTues, only those in simplified chinese are displayed correctly.
When I use some tag editor to display the tags, I can see them in traditional chinese. But it just doesn't show correctly in iTunes, and I have to use those editor to change them to simplified chinese so that I can read them in iTunes.
