As long as you deal with Java Strings, there is no encoding issue, they store any Unicode. Encoding is interesting, when you serialze a Java document to a byte stream or similiar - this is, when you need to choose the encoding, you like to have, with the apropriate Java methods.
FYI: XML documents are transfered to Tamino and received back from Tamino by the Tamino API for Java in utf-8.
Hope this helps!
