[saxon] how to make this transformer output UTF-8?
|

xmlSource is a stream containing UTF-8 data. It appears that the output
does not contain the proper UTF-8 characters. Can anyone give me an idea on
how to get this translate method to output UTF-8 correctly? I've been
working on this for a while and would greatly appreciate any help you could
give me.
Thanks a lot!
