You have the right suspicion. It must certainly be something inside the
servlet that affects the encoding of the characters. The input data is
probably in UTF-8 (your Maori character as two bytes) and the data
passed to FOP is probably incorrectly forced to ISO-8859-1 (or another 1
byte encoding) somehow. Without seeing the Java source code that handles
the transformation it's impossible to just point you to the right place.
Look out for things like the use of String.getBytes(), InputStreamReader
or byte[]. They can (but don't have to) indicate problem spots. Please
refer to our demo servlet [1][2] and the embedding examples [3] for
recommended patterns. If you don't manage to identify the problem, post
your code here.
