There's probably a mapping from the GStreamer tag (GST_TAG_LOCATION) to
the right vorbis tag ("LOCATION", "LOC?", "GPSPOSITION"?) missing.
Please file a bug about that, preferably with a link to references
suggesting what the proper vorbis tag most likely should be (for example
a spec or examples of other applications using a particular tag for
something similar).

All strings you get from GStreamer or pass to GStreamer are supposed to
be UTF-8 unless explicitly stated otherwise.
