[jdom-interest] CDATA inconsistency

[Malachi de AElfweald]

Ok, so the real issue is that the characters are being added as
binary data instead of as Java chars then? That would mean that
grabbing the data from the initial source would be the problem?

So, if the original data were grabbed via a BufferedReader via
an InputStreamReader using the correct encoding, would that not
make sure that the data had the correct surrogate pairs internally,
since they would all be valid Java characters?
