[Qt-qml] UTF-8 vs. other encodings with XMLHttpRequest

[ari.koivisto at nokia.com]

Hi,

I've run into problems in how qml handles character encodings with XMLHttpRequest.

The web service I'm using returns either a block of text with following response header "content-type: text/plain; charset=iso-8859-1" or a text/xml response with "<?xml version="1.0" encoding="ISO-8859-1" ?>" - depending on the service request.

I'm using XmlListModel for the XML response and it seems to be working ok with iso-8859-1, but using the responseText with XMLHttpRequest ends up with non-ascii letters in black diamond question marks.

Looking at the source 4.7.0 beta 2 (qdeclarativexmlhttprequest.cpp):
---clip---
QString QDeclarativeXMLHttpRequest::responseBody() const
{
    QXmlStreamReader reader(m_responseEntityBody);
    reader.readNext();
    QTextCodec *codec = QTextCodec::codecForName(reader.documentEncoding().toString().toUtf8());
    if (codec)
        return codec->toUnicode(m_responseEntityBody);

    return QString::fromUtf8(m_responseEntityBody);
}
---clip---
It is trying to find the decoder with the response body and failing as the charset is set in the headers. Shouldn't the header charset be used here?

Best Regards,
Ari
