void MyEventSaxHandler::characters( const XMLCh* const chars
, const unsigned int length)
{
if (!strcmp(_curElt, "argument"))
{
_event->addArgument(_tag.c_str(), StrX(chars).localForm());
}
}
The translation is done like this:
XMLString::transcode(toTranscode)
I'll need to investigate to find out the buffer size of evt.

This function works with char*, but the MyEventSaxHandler::characters()
handler receives Unicode characters; how do you translate them? Can you
post the code for that function too?

You should know it; how do you get the buffer that the evt pointer points to?
