Why doesn't Xerces-C++ work with UTF-16 ?

[Rafael Sousa (Ext_Altior)]

Hi all!
 
When running the samples in the Xerces-C++ library, namely SAX2Count (with 
validation), I get the following error:
 
Warning at file /home/rsousa/XML_Schema.xsd, line 1, char 40
Message: Encoding (UTF-16, from XMLDecl or manually set) contradicts the 
auto-sensed encoding, ignoring it
 
In XML_Schema.xsd, the first line is:
 
<?xml version="1.0" encoding="UTF-16"?>
 
If I replace it with UTF-8, no error occurs. But I really need UTF-16...
 
Does anyone know why does this happen? Shouldn't Xerces-C++ automatically use 
UTF-16 encoding?
 
Thanks in advance,
