No, they didn't "get" the bitmaps! The fonts got superseeded by WQY
ZenHei and AR PL UMing and that is indeed standard behavior and not a
bug! We don't ship proprietary fonts. If you want to use them, then you
are on your own!

No, your "problem" is not a problem at all, but depends on how you set
fontconfig. Again, we only ship WQY ZenHei, AR PL UMing, AR PL UKai and
WQY Bitmap Song as Chinese fonts. And of course we configure the system
so that these fonts get preferred. Therefor it is expected behavior and
not a bug!
