Bin Dai updated XERCESC-1839:
-----------------------------

    Description: 
The xml file (test.xml) below has two french letters (marked here as ','). 
file test.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<Project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<!-- d'�t� 2008 -->
</Project>

When I ran DOMPrint test.xml or SAMPrint test.xml, the fatal errors occured and here \
is the output:

 DOMCount test.xml

Fatal Error at file /home/bdai/xfndry/HEAD/env/xerces-c-3.0.0-x86_64-linux-gcc-3.4/bin/test.xml, \
line 1, char 40  Message: invalid byte 't' at position 2 of a 3-byte sequence

Errors occurred, no output available

Regardless where I move the gilty line, the line number (=1)and column (=40) do not \
change. Debugging through the code, I see that XMLReader.cpp keeps track of the line \
number and column number, but it calls XMLUTF8Transcoder.cpp where it peeks each \
byte. When it realizes that the byte is not an UTF8 code, it throws an exception. \
XMLReader never updates its line and column numbers.

If the error occurs after 4K(hex) bytes, the line will be updated to a new line, but \
will be unchanged inside the second 4K(hex) bytes regardless where the error is.

It would be helpful to report the real line number.
