I took a quick look at the ID3 specification reveals that Unicode was
not introduced until ID3v2, so determining the encoding before that was
not possible.

With ID3v2, the possible encodings are ISO-8859-1, UTF-16 + BOM,
UTF-16BE (no BOM) and UTF-8. 

When reading ID3v2, MP3Info should present the title as a Unicode object
(though I have no idea if it actually does this or not). 

When reading ID3v[0,1], MP3Info would have no choice but to present the
title as a byte string.
