No, that doesn't sound like the job it was meant for.....

....for this reason, and also because it's not designed to work on  
XML documents.

If you can extract the relevant fragments of the file into plain text  
(UTF-8) files, you can run them through a Unicode->Unicode mapping  
using the txtconv tool; no need to go to 8-bit encodings.

There might be other approaches, too; it depends quite what your data  
is like, and what transformations you're trying to achieve.
