Where are you checking the content of the XML?
It seems that platform's default encoding is not able to identify those characters and hence dispalying those as "???". Sometimes you get some invalid characters (like null), in the XML file and when platform's default encoding could not identify those characters then they get displayed like "?". Please check the content of the XML to verify it does not contain any invalid XML characters (sometims null). You may try to log the XML in database and in OSB to see it's content.
