Error while processing XML ; ORA-19202: Error occurred in XML processing

Question

We have an application, which sends an XML to DB for processing.
While it works in general, it is failing, when special characters are present in the text node
see example below
<?xml version="1.0" encoding="UTF-8"?>
<Query>
<Group>
<Value>  %</Value>
</Group>
</Query>
Db throws following error while parsing this xml
XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00217: invalid character 15573180 (U+EDA0BC)
How to fix it?

Answer 1

The following works for me on 11.2.0.2, db charset AL32UTF8 :
test_sample.xml, encoding UTF-8 :
<?xml version="1.0" encoding="UTF-8"?>
<Query>
<Group>
<Value>?%</Value>
</Group>
</Query>NB : the characters behind the "?" got lost after posting, they're actually 0xF09F 8C82
