Shorter as measured by... ? Number of characters in
it? Since JDOM is not a parser, encoding/decoding
issues are dealt with by the underlying parser;
default being Xerces when using JDK 1.5+.

I doubt JDOM has anything to do with the problem. By
the time it gets data from parser, it's all in java
chars/Strings, decoded from input (byte stream
usually) as necessary.
But without a sample document it is impossible to know
what exactly goes wrong.

The most common error is that the encoding declaration
in the xml document is wrong, and contents are encoded
using some other encoding.
Second common problem is developers printing out text
to console, and console being unable to display it
properly.

No kidding, that's about worst piece of code anyone
could write. I wish compilers would refuse to compile
it. :-p
If it worked as expected, your input data was broken,
and you were just lucky that 2 wrongs made right.
