Script Lecture en cours de VLC, UnicodeEncodeError

Salut,
Toujours dans mes bidouillages de diffusion de flux vidéo/audio, j'ai besoin d'afficher le titre de la musique diffusée, un script remplissant cette fonction a été développé en python (à la base pour windows mais bon, il ne devrait pas y avoir de problème sous linux), j'ai tout mis en place (l'interface lua de VLC, le script et quand je l’exécute, il me créé un fichier LectureEnCours.txt, mais dès que je lance la lecture, il me sort:

Traceback (most recent call last):
  File "NowPlaying.py", line 110, in <module>
    getInfo()
  File "NowPlaying.py", line 49, in getInfo
    root = ET.fromstring(r.text)
  File "/usr/lib/python2.7/xml/etree/ElementTree.py", line 1300, in XML
    parser.feed(text)
  File "/usr/lib/python2.7/xml/etree/ElementTree.py", line 1640, in feed
    self._parser.Parse(data, 0)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 1543-1544: ordinal not in range(128)
 



Il n'arrive donc pas à En/Décoder les caractères envoyés par VLC dans le flux XML car supérieurs à 128 ?! Que puis-je y faire ?

Le script en question
