I believe this has shown up in Qt 4.7. We did not run into this with earlier versions of Qt, but we could have just been lucky.

Description
I'm sure this can be argued, but I would expect BOM a common thing with XML and would expect the Qt's XML processing to handle it.
Small Qt App to show the difference in behavior. Attached in xmlBom.zip.
C:\Users\jwild\Dev\Qt\xmlBom\xmlBom.zip
Only 1st string without BOM has it's elements listed. Here is the main
code of the test.
void MainWindow::list()
{
QString s = "Hello World";
QString xmlWithoutBom = "<body><element>Hello</element></body>";
QString xmlWithBom = "\xef\xbb\xbf<body><element>Hello</element></body>";
QXmlStreamReader xmlReader;
s = "Parse without BOM: \n";
xmlReader.addData(xmlWithoutBom);
while (!xmlReader.atEnd()) {
if (xmlReader.isStartElement()) {
s += "Start Elem: " + xmlReader.name().toString() + "\n";
}
xmlReader.readNext();
}
s += "End Parse without BOM\n\n";
s += "Parse with BOM: \n";
xmlReader.addData(xmlWithBom);
while (!xmlReader.atEnd()) {
if (xmlReader.isStartElement()) {
s += "Start Elem: " + xmlReader.name().toString() + "\n";
}
xmlReader.readNext();
}
s += "End Parse with BOM\n\n";
textViewer->setPlainText( s );
}
