I did the same thing back in the day in iTunes with Japanese artists etc. But iTunes had comment and "Sort Artist" and "Sort Title" fields that solved your first 2 problems and the iPod supports the same set of unicode as the Mac, so it worked out pretty well. It also helped teach me Japanese!

People complained about the bloat in iTunes, but at times all those features did come in handy! I'll miss the depth of features once Apple finally ends up replacing the Mac music app with a port of the dumbed-down streaming service they have on iOS.
