no chinese language display for the music playing page

i am a big huge fan of meizu
and really feel very satisfied with my new m6

but still got one problem with my m6
there are lotsa unreadable words for my chinese songs displaying page instead of chinese words...
but there is still nice chinese words display for my chinese songs at menu..

please enlighten me

Do they show up as ?'s ? If so, it might be a ascii/unicode issue in how the firmware was programmed.
