known bugs in libtag.so.1.4.0
------------------------------
1) TagLib::ByteVector::setData without updating size(actually not a bug
but should use with caution since this effects the behavior of other
methods such as at & clear & resize)
2) TagLib::String::data encodes in UTF16LE while specifying UTF16BE
3) TagLib::ID3v2::RelativeVolumeFrame() defined in
relativevolumeframe.h but not implemented in relativevolumeframe.cpp
4) TagLib::ID3v2::UserTextIdentificationFrame::find not exported
properly
5) TagLib::MPEG::Properties::protectionEnabled() defined but not
implemented
