Expected: Correctly parse mp3 file with big endian UTF16 tags so tags such as
title and album name show up in gtkpod corrrectly.

Instead: In gtkpod the mp3 text fields such as title and album name show with
Chinese characters.

Root cause: The mp3 file has string fields with two byte order marks. The correct
one is the second one.

                     ll llbb bb

llll = little endian byte order
bbbb = big endian byte order

libid3tag utf16.c:id3_utf16_deserialize() assumes there is only one.
