the 'Ð' that appears in totem for example is supposed to be a '–'.

mplayer shows the name correctly, GStreamer doesn't.

The char in question has a value of D0, that is a Ð in UTF8, but it is stored into one of the (C) atoms that needs some special parsing that is yet unhandled in qtdemux. Will look into it.

I learnt something. Do you have some details on what that parsing is supposed to be?

'User Data Text Strings and Language Codes' section from the qtff pdf: https://developer.apple.com/library/mac/documentation/QuickTime/qtff/qtff.pdf

The section above that has a few examples of the (C) metadata atoms.

    qtdemux: handle tags in mac encoding
    
    Check the charset from (C)*** tags and set the charset
    to convert from MAC encoding if suitable.
