It has come to our attention that jit.qt.movie's id3 tag features rely on Apple technologies which don't work with Unicode strings. As such, id3 tags which use non-English characters are inaccessible via those messages. Which is unfortunate.
At the link which follows is a new object, 'metatag', which is dedicated to the manipulation of metadata in media files via the 'taglib' library (http://developer.kde.org/~wheeler/taglib.html).
Currently it supports both ID3v1 and ID3v2 for MP3 files, Ogg Vorbis comments and ID3 tags and Vorbis comments inFLAC, MPC, Speex, WavPack and TrueAudio files.
Help file is included, as are binaries for Mac and Windows, and source code. This object is in beta, but should be stable enough for production use. Thanks for any feedback and testing!
