I don't believe so, at least from the Java perspective. DOM passes 
everything thing in as a String. All the underlying DOM implemenation
needs to do is check what encoding is used for that string. If it finds
something that is not US-ASCII then it sets the useBlueberry flag
internally and off it goes. As for other languages, can't comment, but I
suspect at least similar string handling capabilities exist for dealing
with internationalisation issues (even just look at the CodePage of the
underlying system for a tip)
