HI Michael,
Would you mind to let me know how you connect the runeaudio from iPad? Through Web? Or other MPD app?
For your Chinese / Japanese song, is it in WAV file formation? (For me, the problem just happen on WAV file format with Chinese tag).
About your display issue on attached display, I don't know whether is it the same issue as mentioned in great-compatibility-on-double-byte-character-display-on-0-4-t3347.html#p12914.
Best Rgds.,
