Hi.
I've earlier written some serialization code that used the SAX API of
Xerces-C for reading, and a modified SAXPrint example for writing stuff
back out.
I've started blowing the dust of this thing. Last time I made sure it
compiled and ran with Xerces-C was with version 1.3.0, so now with 1.5.0
and G++3.0, I decided to clean stuff up.
The problem is local codepage characters.
I have tried reading in a file that contains Norwegian specific
characters (���), but I keep getting a segmentation fault in strlen,
deep within the SAX code:
<STACKTRACE>

</STACKTRACE>
I have tried with the encoding both in ISO8859-1 and UTF8, running the
textfile thru iconv for conversion, but neither works:
---------------8<------------------
<?xml version="1.0" encoding="UTF8"?>
<person>
<name>Ola Børre</name>
</person>
---------------8<------------------
<?xml version="1.0" encoding="ISO8859-1"?>
<person>
<name>Ola B�rre</name>
</person>
---------------8<------------------
Is this a known problem with G++3.0, Xerces-C 1.5.0, the old SAX API or
some FAQ I've missed?
