Does our nav/audio system support the display of unicode characters on file names? I listen to a lot of chinese music in the car and all i get is a blanked out name for the song titles and artist names.

I was wondering if there's something i need to turn on to enable it or is it just not supported at all which would weird considering it's a japanese made car. I'm sure the JDM market would require the audio system to support unicode characters for japanese music titles.
