[news.eclipse.tools.emf] Resource serialization options

[alr@xxxxxxxxxx (alr)]

I'm actually using XMI serialization, and i can't load serialized data
coming from a save operation. XML parser can't read the stream it has
previously written. The error seems to come from special characters using
in serialized data.

I was asking, if could change the encoding format from standard ASCII to
anything else that support special characters, but i was enable to find
any documentation about the save/load options. Could you please help me.
thanks


Briefly, here it is what i'm using
(1)
Resource res = resourceSet.createResource(uri); ...
res.save(outputStream,Collections.EMPTY_MAP);

and then,
(2)
Resource res = resourceSet.createResource(uri); ...
res.load(inputStream,Collections.EMPTY_MAP);

and here it is the error, i've got :

org.xml.sax.SAXParseException: Erreur de conversion de caractère :
"Illegal ASCII character, 0xe9" (le numéro de ligne peut être trop bas).
