Tomcat needs a flag that tells it to use UTF-8. If you don't set that
various problems happen, including this one. Look on the solr wiki for
Tomcat and UTF-8.
Also, there can't be any blank lines at the top of the XML file before
the XML header.
Can you post a very short XML file that has this problem?
